Compare And Contrast Roses And Roses
In a flower garden, the roses are considered to be the most famous and the queen of all the countless
flowers. Roses vary in different colors that come in white, orange, red, pink, maroon, beige and
yellow. They have very soft and delicate petals with so much fragrance in it that can be used as
perfume. They bloom nicely and attractively in perfect shape that you can't help but fall in love with
it.
Even though there are flowers that match the roses' characteristics such as appearance and fragrance,
they cannot be compared when it comes to their uses and meanings. The petals of a rose can be
combined with milk which is good for the skin. And their colors also have their special meanings

and some are rarely found in carmine–red or yellow.
These Lisianthus flowers begin to blossom during the early summer but there are also some that
continue to blossom during the later days of summer. The fascinating part is this flower can last
from 2 to 3 weeks in a bud vase when it is cut. The Lisianthus flower is also known as Texas
bluebell, Lisianthus, gentian, tulip gentian and prairie gentian.
4. Begonias
Tuberous Begonias or simply Begonias are one of the most amazing species. This specie includes
1,795 different kinds of plants. These Begonias grows best in soils that are moist in tropical and
subtropical areas under the filtered sunlight. But if these plants will be exposed in too much
sunlight, it will only produce a small number of flowers. Although in cooler temperature, some of
these species are being cultivated and grown inside the house to be used as decorative house plants.
However, there are also times that these flowers are grown outside during the summer season to
produce bright and colorful flowers in which there are only sepals instead of

Negative And Negative Effects Of Pollination
Pollination is responsible for keeping humans alive. But many underestimate what pollination does
for them, and how complex it is. There are mainly two types of cross–pollination and that is
generalist pollination, where different species of pollinators go to the same flower, and specialist
pollination, where a species of flower relies on a single specie of a pollinator. Flowers have adapted
to the needs of pollinators, but specialized flowers have adapted to suit the single specie pollinator
that comes to them. But because the flower only has this specie of pollinator, it can have both a
negative and positive effect on the plant and pollinator. Plants and pollinators have a relationship
that helps keep ecosystems alive, so they are very ... Show more content on Helpwriting.net ...
Another positive to selective pollination is that the animals that pollinate the plant will have a food
source that they will be able to get to, and if the animal spreads the pollen and increases the range of
the plant, the animals would have more food sources. When a flower is specialized, it has
opportunities to increase diversification rate, the range of pollen, and range of seed dispersal
(Armbruster, 2014). Angiosperms can also change which animal it specializes for (Niet et al., 2014).
The Costus is a plant that will permanently switch from a bee pollinator to a hummingbird because
hummingbirds can transfer pollen more efficiently (Niet et al., 2014). Angiosperms usually
specialize in a pollinator because it will benefit them, but it also benefits the pollinator because the
flower can give the pollinator rewards for coming, but sometimes specializing is not a good thing.
Even though selective pollination can be good, it also has some negative effects. Sometimes,
selective pollination can lead to reproductive isolation (Armbruster, 2014). This causes the species
of plant to have to self–pollinate, which lowers genetic diversity and sometimes range. It can also
affect the pollinator because they have to find another food source, and if they don't, the pollinators
can start dying off. Or if the species pollinator starts to die off,

Factors That Affect The Growth And Germination Rates Were...
Plants are an essential part of survival for humans and animals and contribute significantly to
various areas of the lives of organisms. In order to better understand the different plants and its
requirements the growth and germination rates were investigated. The hypothesis stated that if the
dicotolydeons and monocotyledons are placed in the same environment and watered regularly, then
the dicotyledons will have a faster growth and germination rate.
In order for plants to survive, it is a necessity for the process of photosynthesis to occur.
Photosynthesis is the process wherein plants create oxygen and food for themselves (glucose) using
carbon dioxide, water and energy from the sun. Once this process is completed, plants are able to
grow using the nutrients provided by photosynthesis.
Word equation: carbon dioxide + water (SUNLIGHT AND CHLORYPHYLL) glucose + oxygen
There are many factors that affect photosynthesis such as light availability, carbon dioxide
concentration and temperature. Light is a limiting factor as if there is not enough light available, the
rate of photosynthesis will decrease. This is because without the light, the chlorophyll (not be
created) will be unable to absorb energy from the sun, resulting in no food which is required for
survival. Temperature plays an essential role in photosynthesis as well. As the temperature increases,
so does the rate of photosynthesis. As it is a chemical reaction, an increase in temperature will cause
enzymes and

Protect Pollinator Populations
Why Regulations Are Needed to Protect Pollinator Populations
Currently, an estimated 3.2 million tons of pesticides are used each year (Hicks, 2012).
Pesticides are normally misused by people with little knowledge or care for their harmful effects.
Without effective enforcement of regulations, pesticides are easily spread beyond their projected
areas. According to research, the overuse of pesticides causes many human diseases, animal
diseases, and disruptions in our ecosystem. Well defined regulations, along with consumer
education, could limit the misuse of pesticides and protect our fragile pollinator populations from
continued decline to help ensure future food sources for many generations to come.

Fifty–two percent of pesticides are in your drinking water due to the use of chlorine to "disinfect it."
Farmers only use 17% (Lah, 2011). Chlorine is also harmful to bees, which are the main animal
species that pollinates. Most chlorine contains neonicotinoids which are chemicals that are active
ingredients in many pesticides. Multiple pesticide products used by homeowners have manufacture
recommended rates for applications 120x higher than rates for agriculture crops (Jennifer Hopwood,
2012).
An estimated 2.2 million people are at risk due to exposure from agricultural pesticides, with the
majority of this population being located in developing nations (Hicks, 2012). Most people affected
by pesticides contract them by consuming food contaminated with a high concentration of
pesticides. In humans, pesticides can cause headaches, blurred vision, vomiting, abdominal pain,
immune system suppression, blood and liver diseases, asthma, and even nerve damage. Pollinators,
and other animals living around the streams where pesticides accumulate experience many of these

Effects of Flowers with Scent Versus Flowers without Scent on Insect Activity
Flower communities are an example of a limited ecosystem that vary from one to another based on
species of flower as well as microclimate differences. The main component of a flower community
is the flowering plant itself. This plant is the main dictator of all activity in the community. Other
aspects of this limited ecosystem include the species that interact with this plant and the resources it
provides. These species may then also interact with each other influencing aspects of the ecosystem
such as species behavior, resource abundance, and competition (Watt, 1947). As a community the

The flower is in bloom from September to November in habitats with relatively dry soils receiving
little sunlight. Although the flowers do not produce a scent, they do provide a nectar source and are
known to attract butterflies. It is also know to be a plant that attracts predatory insects that prey upon
pest insects the same as the Sweet Everlasting ( Pseudognaphalium obtusifolium). Additionally, it is
of special value to pollinators, and known to attract large numbers of native bees ("Native Plant
Database," n.d.).
The ability of both of these flower communities to exist in similar habitats makes them ideal for
comparing differences in insect activity without the influence of outside factors such as temperature,
light, and humidity. Both flower communities are also known to attract similar species, which
allows the quantity of species visiting one site to be easily compared to the quantity of species
visiting the other site. This is essential because the study aims to determine whether the property of
scent, characteristic of the Sweet Everlasting (Pseudognaphalium obtusifolium), had an effect on the
amount of species interacting with each flower community. If certain species are attracted to scent,
then the sweet everlasting will attract larger numbers of species than the white aster
(Symphyotrichum ericoides).

For this study two sites were chosen to compare the different insects, spiders, and other invertebrates

Arsenic Contamination Essay
Introduction
Beside the natural activities, almost all human activities also have potential contribution to Arsenic
contamination in the environment as side effects occurs in many parts of the world and is a global
problem. In many areas As level has crossed the safe threshold level. Large–scale groundwater
pollution by geogenic arsenic (As) in West–Bengal and Bangladesh has recently promoted this
element into an environmental pollutant of prime concern. Epidemiological studies have
documented various adverse effects on the human population. Arsenic contaminated soils,
sediments, and sludge are the major sources of arsenic contamination of the food chain, surface
water, groundwater, and drinking water (WT Frankenberger & Arshad, 2002). Other potential
sources of arsenic contamination are the chemicals used extensively in agriculture as pesticides,
insecticides, defoliants, wood preservatives, and soil sterilants (AZCUE & NRIAGU, 1994).
Currently available techniques for the remediation of As contaminated soil are very expensive and
time–consuming, often hazardous to workers, and capable of producing secondary wastes (LOMBI,
ZHAO, DUNHAM, & MCGRATH, 2000). Phytoextraction, the use of green plants to clean up
contaminated soil, has attracted attention as an environmentally– friendly, low–input remediation
technique. It uses plants that extract heavy metals from the soil and accumulate it in the harvestable,
above ground biomass.

By using maths and statistics, he was able to determine an average, for every three purple flowers
one white flower will occur, a ratio of 3:1.
Gregor Mendel first wanted to achieve a pure breed of flowers, but also wanted to observe the
outcome by crossing the white and purple flowers. For this, we have to understand the basic
principle of how the pea plant fertilizes itself. The stamen is the male part of the plant. The stamen
of the plant is drop pollen into the plant when the start to mature. The pollen falls upon the pistil,
which is the female region of the plant. It then fertilizes the plant and becomes matured plant.
However to cross–fertilize the pea plants Gregor Mendel used a slightly different method whereby
he opened an immature pea plant. Mendel then took out the stamen before they could become
mature and drop pollen upon the pistil. Thereafter using the pollen, which he had taken out, he then
dusted and brushed the pollen on to the pistil of another pea plant transferring them with the aid of a
small brush. The cross–fertilizing of the two plants was named as the parental generation (P) as they
were the first to be pollinated and fertilised.
He transferred and cross–fertilized pea plants, which only had white and purple flowers. He was
very careful within his experiment and insured the controls were accurate and precise at all time.
This can be found within his journal Versuche über PflanzenhybridenVerhandlungen he mentions

Viola Odorata's
In a controlled experiment, how is a plants growth affected by its surroundings? Environmental
factors such as light, water, temperature, and nutrition all take part in plant growth. But do plants
affect each other? If there are three Viola odorata's in a container, then they will grow faster and
more efficiently compared to a container holding nine Viola odorata's whereas they would most
likely absorb more water and other environmental factors.
A Viola odorata is an annual plant that is also known as a sweet violet 'Wellsiana'. These plants

This is not to be confused with plant fertilization which is a common mistake. For normal growth
plants are in need of these eighteen elements: hydrogen, carbon, and oxygen which are found in air
and water. The next six elements are known as macronutrients: nitrogen, potassium, phosphorus,
calcium, sulfur, and magnesium which are found in soil. The last nine elements are called the
micronutrients: iron, zinc, molybdenum, nickel, manganese, boron, copper, cobalt, and chlorine
which are found in the soil. All these elements are crucial. Majority of the plants nutrients are
dissolved in water and immersed by the roots. Active absorption is important and essential for the
plant to grow healthy, but the nutrients can be absorbed passively. Some factors that may affect the
absorption of nutrients throughout the roots are the soil pH, type of ion, solubility of ion pairs,
oxygen, water, soil, sugar supply, temperature, and plant stress.
In conclusion, if a container holds a total of three Viola odorata's and absorb more water and other
environmental factors that contribute to plant growth and development, then they will grow faster
and more efficiently than a container that carries nine Viola odorata's that will take in less water,
sunlight, and nutrients since they are all fighting for it. The fact that all the environmental factors
play such a key role in plant growth signifies their importance and the very reason that plants would

Jaws are believed to evolved from the first pair of gill arches. The presence of jaws permits a
predatory lifestyle. Early bony fishes or lobed finned fishes had lungs. Amphibians were the first
group to have jointed appendages and to invade land. Amphibian means living both on land and in
water. Besides the jointed limbs they have other features that are not seen in the fishes. Eyelids that
keep the eye moist, sound producing larynx, and ears adapted to pick up sound waves. Amphibians
have a great variety of reproductive strategies. This variety as well as the adaptations noted above
made them successful colonizers of the land environment. Reptile are the next step in the
evolutionary tree of chordates. The most outstanding adaptation of reptiles is that they have a means

that is at least 10 inches in diameter and at least 1 foot deep. This will provide sufficient room for
root development.
In addition to the container, you also need the appropriate soil mixture and draining mechanisms.
For the best drainage, fill the bottom of your container with 2 or 3 inches of gravel. On top of the

ingredients you will find described on soil bags are N–P–K–that is, nitrogen, phosphorus, and
potassium. Without going into too much detail about the role of each element in plant growth, I will
tell you that an average vegetable will grow fine in a 10–5–5 mixture. This ratio, too, will be easy to
find at your local nursery.
Once you have the gravel in the bottom of the container and the soil on top, you are ready to

Wormwood, or Artemisia Maritima Essay
Wormwood, or Artemisia Maritima, is a low maintenance plant that is easy to grow. This plant is
great for beginning herbologists. In the wild, sea wormwood grows along the seashore in Europe
and Asia. Wormwood is a hardy plant that can tolerate drought, maritime exposures and
temperatures as low as –15C. It has a sweet lavender–like smell but is very bitter to the taste. It is
easy to identify from a distance by its silver–gray colour. It is a flowering plant, growing close to
two metres high. The leaves are narrow, covered with silver velvety fur. It has small yellow oblong
flowers, containing three to six florets, in August and September. They are hermaphrodite and are
pollinated by the wind. In the following, I shall ... Show more content on Helpwriting.net ...
In addition to treating the wizarding community for their ailments, I could use a wormwood potion
to help increase the appetite of cows as well as repel slugs, insects, and mice. Its fragrant branches
can be put into linen closets and mattresses to drive out moths and fleas, and in shoes to prevent
tired feet.
I grow this plant in light sandy, medium loamy, salty soil that is well–drained but moist with a pH of
6 to 7.6. I keep it in full sunlight. I sow the seeds from late winter to early summer in my
greenhouse. I must ensure that the compost does not dry out. When they are large enough to handle,
I plant the seedlings into individual pots. There can up to 50,000 seeds on each stem which are
viable for three to fours years! I keep them in the greenhouse during their first winter.
In the late spring to early summer of their next year, I plant them outside. The plants must be planted
two feet apart. I prune half of the ripe wood in July or August and divide the plants in the spring or
the fall. They regrow from ground level each spring. It is difficult to manage wormwood once it is
established, as it reduces biodiversity.
This plant is poisonous in large qualities and must be kept out of the reach of children and pets.
Ingesting small quantities may cause nervous disorders, convulsions and insomnia. The scent may

Tulips have been placed with a class of plants that shape foods grown from the ground called
angiosperms, which initially dates approximately 100 million years back. Most plants recreated the
way our forefathers would have done it, through spores that made hereditarily indistinguishable
clones of their folks. Yet, angiosperms hit upon another method for spreading their qualities that
gave them a transformative favorable position. They delivered female cells that remained on the
plant and male cells in dust that could be spread to treat neighboring plants. In the meantime, the
angiosperms made themselves appealing to bugs, flying creatures, and honey bees, which brought
about these animals conveying dust, starting with one plant then onto the next, making an
unfathomable blast of assorted variety. Through some secretive, however exact transaction of

Answer: Animal pollinated plants are strong, which make them easier to be found during evidence
collection but not a plentiful as wind pollen. Wind dispersed pollen produces large amounts of
pollen, which makes it easier to be found in forensic science during evidence collection, but it's
harder to direct find a suspect with this type of pollen. Water dispersed pollen absolutely has to stay
in water or it will degenerate. So this type of pollen doesn't exactly help in forensic science unless a
victim was drowned.
17)Describe how pollen can be used to determine if a crime occurred in the city or in the country or
during the day or night.
Answer: Pollen can be used to determine if a crime occurred in the city or in the country or during
the day or night because country & city conditions are different. The air is more polluted in the city
than in the country, which can affect plant cycles. Also, the city has a lot more sidewalks & other
pavements, shaded areas and not very much fertile soil for plants to even grow. This majorly limits
the types and survival of plants in that environment. Plants mostly flower in the daytime opposed to
the night time because there is sun only in the daytime. This means that there is more pollen in the
air during the

The Great Family of Araceae
One living organism that has a very important function for the environment and all the living
creatures on Earth is the plant. This is because other living organisms such as animals and human
beings greatly depend on them for food and oxygen. Furthermore, they are also able to provide
living creatures the shelter that they need. As well as medicines that can be taken from medicinal
plants. There are approximately 250,000 different species of plants and they are all part of the
kingdom Plantae which has many different types. ("Plants in Peril – Plants and People", n.d., p.
xx)One of them is the Angiosperms which can be further classified into Magnoliids, Eudicots, and
Monocots. Under the Monocots are further classifications and one of them is the family of Araceae.
("Araceae", n.d., p. xx)
One interesting family that belongs to the division of flowering plants or Angiosperms is the
Araceae. The term Araceae came from the word Arum, a plant genus, and it also came from Aron, a
common name for plants in the said genus. The suffix –aceae is added to the name since it is the
suffix used in constructing the name of the families of plants. ("Araceae", n.d., p. xx) This is where
the name Araceae came from. The family Araceae has its own classification. It belongs to the big

The Importance Of Gene Imprinting
Gene imprinting is an epigenetic phenomenon when two alleles of a certain gene are expressed at
different level depending on their parent–of–origin. Gene imprinting has been documented in
mammals and flowering plants. In the 1980s, biologists' attention to imprinting has greatly increased
due to the recognition of its importance during mammalian development [1]. Imprinted genes
regulate cell growth, cell signaling, cell cycle regulation, and influence nutrient acquisition and fetus
growth. In mammals, many imprinted genes are found in the placenta and brain, which is consistent
with growth and neurodevelopmental defects observed in human imprinting disorders [2,3].
In addition to mammals, gene imprinting is also found in flowering plants. ... Show more content on

The angiosperms (flowering plants) are the most diverse group of land plants, with over 250,000
species [5]. Double fertilization is a unique feature distinguishing angiosperms from their seed–plant
predecessors (gymnosperms). This feature might have provided angiosperms an evolutionary
advantage to become the dominant form of land plant life, although the selection force of this trait is
poorly understood.
Unlike animals that define all cell lineages during embryogenesis, plants are able to establish novel
cell fates throughout their entire life cycle, especially during sexual reproduction. Sexual
reproduction in flowering plants comprises of a process divided into three phases: sporogenesis,
gametogenesis and embryo–/ endosperm–genesis.
Sporogenesis is initiated in both male and female reproductive tissues. In ovule primordium, a
subepidermal nucellar cell differentiates into a megaspore mother cell (MMC), the MMC then
undergoes meiosis to form four haploid megaspores. Only one megaspore survives to become
functional megaspore (FM) and proceeds to gametogenesis, while the other three degenerate. In
stamen primordium, one subepidermal nucellar cell gives rise to a microspore or pollen mother cell
(PMC). The PMC then undergoes meiosis to form four haploid microspores which will continue to

Anatomy of an Orchid Flower
Anatomy of an Orchid Flower
Despite the astonishing diversity found in the thousands of wild species and man–made hybrids,
orchid flowers show an unmistakable family resemblance. Orchid flowers are generally bilaterally
symmetrical–only a single imaginary line can be drawn through a flower to create a mirror image.
A typical orchid flower has three sepals (the outer segments that protect the bud before the flower
opens), alternating with three petals. The petals and sepals may be similar or not, showy or
inconspicuous.
The middle petal, which is always opposite the column, is usually quite different from the others.
Called the lip or labellum, it comes in a variety of shapes, depending on the species, and can be

So in appealing to sex, these orchids limit their potential pollinators, which would seem to be a
reproductive disadvantage.
Despite the apparent drawback, sexual deception has evolved several times in different types of
orchids. So there must be some selective advantage, and researchers Salvatore Cozzolino and
Giovanni Scopece of the University of Naples Federico II, Steven Johnson of University of
KwaZulu–Natal (South Africa) and Florian Schiestl of the University of Zürich appear to have
figured out what it is.
Schiestl and his team observed populations of 31 orchid species with varying pollination strategies
in Italy and Western Australia. They measured the amount of pollen that was taken from each
orchid, and the amount of pollen that made it to its intended destination –– another orchid of the
same species.
They found that populations of sexually deceptive orchids had higher "pollen transport efficiency"
than the species with multiple pollinators. In other words, a higher percentage of the pollen that was
taken from sexually deceptive orchids actually made it to another orchid of the same species. The
orchids with multiple pollinators had more pollen taken from their flowers, but more of that pollen
was lost –– dropped to the ground or deposited in flowers of the wrong species.
So it appears that specializing with

The Breeding of the Red-Fleshed Apples
The breeding of the red–fleshed apples was originally from Kazakhstan and improvements of the
apple was breed in order for the breeders to produce a apple that has high in Vitamin and as a
healthy diet snack. The scientists have collected the apple's seeds in order to let those seeds to grow
in New Zealand. The red–fleshed apples were usually small back in Kazakhstan and it has a
different taste which was a bit bitter and had a lack of quality in the commercial marketing. Also
they have improved the apple's taste just by crossing the original red–fleshed apple with another
white–fleshed varieties fruit in order to improve the characteristics of the apple since it will be
important for commercial and consumer with its long storage life. Generally, the red–fleshed apple
will breed in order to improve the quality of the apple and also to provide nutrition which are high in
vitamins and antioxidants, which then it reduces the risk of some diseases, but there are some red
fleshed apple that can be healthier than other apples that have been produced. Although, breeders are
able to use genetic information in order to make the breeding process faster and more effective. By
investigating the DNA from the apples seed the scientists are able to predict that many apple

The Differences Between Vascular And Nonvascular Plants
Land plants can be divided into three different groups. One of these groups are nonvascular plants
which include liverworts, hornworts, and mosses. The other two which are the focus of this paper
are vascular seedless plants and vascular seed plants. The difference between vascular and
nonvascular plants is that vascular plants have vascular tissue which enables them to grow up and be
bigger than nonvascular plants. The difference between seed and seedless vascular plants is the
presence of a seed. A seed is defined by the 10th Edition of Campbell Biology as "an adaption of
some terrestrial plants consisting of an embryo packaged along with a store of food within a
protective coat." This includes anything from apple seeds to dandelion seeds. The absence or
presence of a seed changes how a plant reproduces and also leads to different advantages and
disadvantages to the plant. Seedless vascular plants include such plants as ferns, horsetails, club
mosses, and whisk ferns. They live in wet environments because they require water for
reproduction. They reproduce through the use of spores. Using ferns as an example the spores are
found on the underside of the leaves. They are found in cases called sori and each sorus holds many
spores which are haploid. Spores are released and they form gametophytes. Gametophytes make
gametes which are also haploid and both the egg and the sperm of the fern are created in the
gametophyte, but in different parts. The egg is made in the

A plant that could essentially lose more than 90% of its molecular H2O, regenerate and begin
growing again after long periods of drought could possibly change how whole nations do
agriculture. Agricultural regions that are rain fed would be able to incorporate an additional growing
season. This can be achieved by leaving the plants that have died from lack of water till the next
year when the rain falls thus causing an early crop that will be simultaneous with planting the next
year's crop or a spread out cropping throughout the year because different plants will be a different
maturation stages. The effects this process will have will ensure that no plant is wasted due to heat
stress. The amount of plants that die from heat stress will vary, never the less implementing the
desiccated crops in with the crops that survive from the current year will benefit yield production.
Resurrection plants can remain in the dead, fringed state for months to years. Even after being
"dead" it can still regenerate, become green and continue to grow. Like the seeds of all angio sperm

there were many magical creatures, with different jobs. One creature who was especially important
in Trantopea was Pepper Mint. She was a large red and white creature, who was a farmer of a very
rare plant that she called mint. At that time mint had only existed in her world. Many of the other
creatures in the forest were very jealous of Pepper and her farm, many even tried to steal it. One
creature in particular, Joseph, wanted Pepper's farm very much. He was also a farmer, but his farm
was not as successful as Pepper's farm, as a result he had devised a detailed plan to steal Pepper's
farm. In Trantopea to seal something from someone all you had to do was take it from them and it
was yours forever, so in this case all Joseph had to do is pick one plant from her farm and the farm
was his forever. One day as Pepper was taking her daily walk, she saw a bush rumble in the forest.
She was very confused, but she continued her walk and eventually forgot about it. What Pepper had
not realized was that there were two little eyes peeking out of the bush and watching her. These two
eyes belonged to Joseph, who was trying to find out a perfect time to try and steal Pepper's farm.
Every day for a month, Joseph would watch Pepper take her walk just to make sure that she took

The Importance Of Plants In Canada
Plants are extremely important to the growth and development of Canada because as a source of
food, the country requires the nutrients the plants provide and they are irreplaceable. Plants are
crucial as they are a component of everything people eat, whether people eat the plants or the animal
they eat or get food from rely on plants. The more food and plants available to better the
reproduction, and therefore more population growth in communities. Having more food available
for the entire population has shown to decrease poverty and increase the overall development of the
community (2). In Canada, there is a large discrepancy between the food security of the southern
provinces and northern territories. This has stuck many northern Canadians in difficult situations
when trying to buy the proper food. There is also an economic factor of food and plants. In current
society, most food in imported from country to country, creating many economic benefits in
countries that import food (3). That money can be used to create a better community and country.
On another level, plants and crops also have religious and symbolic value in our culture, which
helps to increase development on a social level. Increases in variety and quantity can help to
develop communities. Certain pants and foods help to give communities and countries their identity.
For example, many foods are crucial to our identity like maple syrup. Overall, food and plants is
extremely important to Canada as a society

It was in the year 1979 a steroid lactone which was termed as Brassinosteroid was isolated from
pollen of Brassica napus (Grove et al, 1979). Later its structure was determined by different
spectroscopic analysis mainly by NMR, EI–MS, FAB–MS and also by X–ray diffraction, which was
found to be (22R, 23R, 24S)–2α, 3α, 22, 23, tetrahydroxy–24–methyl–β–homo–7–oxa–5α–
cholestan–6–one. Since the discovery of brassinosteroid more than 69 naturally occurring
compounds of this hormone family has been discovered. (Yokota 1999a) BR's are derived from a
common 5–choleston skeleton and the structural difference which is present in the different
members of this hormone family mainly comes from the side chain present in A/B ring and also
from different functional groups present in the ring which is shown in the figure ( Yokota, 1995,

The Spandrels Of San Marco And The Panglossian Paradigm
In " The Spandrels of San Marco and the Panglossian Paradigm: A critique of the Adapationist
Programme" by Gould and Lewontin the article discusses about natural selection not being the
overall general reason for the evolution of species. Gould and Lewontin provide a pluralistic
approach of how species are evolved rather than basing on natural selection. Therefore, these
scientists used the central dome of St Mark's Cathedral in Venice to represent the other possible
explanations of the evolution in species. Most importantly, Gould and Lewontin used spandrels and
other findings as an analogy to parallelize the evolution of organisms as an unintentional byproduct
of the species. Gould and Lewontin introduce spandrels as triangular spaces between the arches and
dome. The spandrel is designed in such a way that is exclusively fitted towards its space. Also, the
spandrel shows severe complexity in intricate designs as well. If one were to look at the detailed
design on the spandrel; he or she would question how the spandrel was able to stay in its shape and
form without losing its detail. This is when Gould and Lewontin declare that the spandrel is just a
simple byproduct of the mounting dome. There was no adaptation of the spandrel to form its shape
and size. The reason why the spandrel is in its form is because it was an unintentional product of the
mounting dome. Gould and Lewontin used the spandrel as a metaphor towards biology to explain
that species are able to have

weeds, the Blood Flowers stem and the leaves beneath the flower are green. It can grow to be as
short as one foot or as tall as three feet from the ground up to the end of the flower. It can be one

flowers on the plant are a lot shorter than the leaves and are also a lot smaller. The flowers have two

or fall (Blood Flower, 2017).
