Which is a common trait among all land plants?
Vascular tissues transport water and nutrients, and provide support
Seeds facilitate survival and dispersal of the species
Flowers facilitate cross-pollination
The embryo is protected within maternal tissues
The haploid phase of the life cycle is the dominant phase
Flowers facilitate cross-pollination
The embryo is protected within maternal tissues
The haploid phase of the life cycle is the dominant phase
Solution
First we see common traits of land plants and then see listed traits in details one by one:
1. Ability to withstand desiccation. Extant land plants have a cuticle and guard cells.
2. Ability to withstand the effects of more intense radiation, particularly DNA-damaging
radiation. Extant land plants have several compounds in their vacuoles that absorb UV. Since the
vacuole of a plant occupies most of a mature cell, this helps protect the DNA in other organelles.
3. Ability to protect their spores from desiccation. Early land plants have spores that are encased
in a sporopollenin wall. Sporopollenin is a very resistant polymer, resistant to UV and almost
everything including desiccation, squashing, etc. To remove sporopollenin from spores, one boils
them in a mixture of acetic and hydrochloric acid.
4. Ability to move solutions from the ground to portions of the plant that are not in contact with
the ground, and from the photosynthetic portions of the plant to non-photosynthetic portions.
Some land plants do this better than others.
5. Ability to support themselves. Aquatic plants float; terrestrial plants cannot do so. Most
terrestrial plants have lignin in some of their conducting cells. There is some debate as to
whether this was selected for by the advantages of growing tall or the need to protect against
embolism in the conducting cells. Since both are important, it seems most realistic to accept that
both contributed to the success of plants with the ability to manufacture lignin, the tracheophytes
or vascular plants.
6. Ability to acquire the carbon dioxide required for photosynthesis from the atmosphere. This
ability is associated with stomatal cells, specialized cells that surround openings (stomates) in the
outer cell layer of land plants.
Now we see Options given one by one:
Vascular tissues transport water and nutrients, and provide support
Transport of Water and Minerals:
The xylem tissue transports water and minerals. It consists of interconnected vessels and
tracheids organized into continuous conducting tubes stretching from the roots to the leaves.
These tubes carry water and minerals to all parts of the plant.
Plants absorb water from the soil through the root and transport it to the stem, leaves and
flowers. Roots have root hairs that are unicellular, thin-walled outgrowths of the epiblema (skin
of the root).
The root hairs are in close contact with the thin film of water surrounding the soil particles.
There are mineral salts such as nitrates, chlorides, sulphates, phos.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Plants originated form green algae, in the primitive
seas.
They can not move, but they have colonised all
environments on the Earth, thanks to different
adaptations.
There are two groups of plants:
Plants without seeds: Mosses and Ferns.
Plants with seeds: Angiosperms and Gimnosperms.
3.
4. Try to think….
1. Plants are unicellular/multicellular living things.
2. Plants are eukaryotic/prokaryotic organisms.
3. Plants do/don’t make their own food.
4. Plants are autotroph/heterotroph organisms.
5. Plants use a pigment called _________ to absorb the
sun light.
6. The process they use to make their own food is called
_________.
5. PARTS OF A PLANT
Plants have usually four parts:
-Roots: absorb water and mineral salts from
the soil.
-Stem: transport substances up and down
trhough the plant.
-Leaves: absorb the sunlight and exchange
gasses.
-Flower: it is the reproductive structure in
flowering plants.
6. CLASSIFICATION OF PLANTS
Plants with Seeds:
Gymnosperms
Angiosperms
Plants without Seeds:
Mosses
Ferns
8. MOSSES
They are the most primitive and
simple plants.
They don’t have vessels to transport substances (they
are “non-vascular plants”).
They don’t have real roots, stem or leaves. They have
very small similar structures called:
Rhizoids (rizoide)
Cauloids (cauloide)
Phyllodes (filoide)
9. They live in very humid places, on the soil, on rocks, or
on the trees’ trunks.
Mosses reproduce asexually, produceing reproductives
cells called “Spores”.
Spores are stored in special capsules on the top of the
plant.
When the capsule is broken, spores fall to the ground
and, if conditions are favourable, they produce a new
moss.
12. FERNS
Ferns are plants with vessels to transport substances
through the stem (they are “vascular plants”).
They live in humid areas as they need water to
reproduce.
They have roots, stem and leaves. Their leaves are
called “Fronds”.
13. Ferns reproduce asexually producing special cells
called “Spores”.
Spores are located in the downside of the leaves,
forimig gropus called “Sores” (soros).
15. GIMNOSPERMS
They have sexual reproduction.
Their seeds are not protected inside a fruit.
Gymnosperms include conifers, ginkgos and
cycads.
16. Conifers are widespread.
They include pines, secuoyas, fir trees and
cypress.
They are evergreen trees, as they lose their leaves
gradually all year round.
They have cones (their flowers) which protect their
seeds.
19. ANGIOSPERMS
Angiosperms have sexual reproduction.
They are plants with seeds wich are protected
inside a fruit.
They usually have bright, colourful flowers.
Most plant products used for food are obtained from
angiosperms.
22. FLOWERS
Flowers are the reproductive organs in gymnosperms
and angiosperms.
Gymnosperms’ flowers are unisexual, and we call
them “cones”. They don’t have calyx or corolla.
Male flower
28. POLLINATION
Pollination is the process by which pollenis transferred
from a stamen to a pistil.
When it happens within the same flower, we call it self-
pollination.
When it happens between two different plants, we call it
cross-pollination.
The wind, water, insects or others animals may help
pollination to occur.

29. Fertilisation is the union of the male gamete
(found inside pollen) with the female gamete
(ovum).
To make this possible, a filament grows from the
pollen grain and it reaches the ovum. The male
gamete goes down this “pollen tube” until it
reaches the ovum inside the ovary.

31. Once fertilisation occurs, the seed is formed
inside the ovary.
Later, the ovary becomes a fruit that contains the
seed.
The fruit may be dry or fleshy, depending on the
amount of water they contain.

33. There are two main types of responses in plants:
Tropisms → Permanent responses which produce
changes in the direction of the plant’s growth. Types:
Geotropism: The response
is caused by gravity.
Phototropism: The response
is caused by light.
Autora: Marta García T.Autora: Marta García T.
34. Hydrotropism: The response is caused by water.
Thigmotropism: The response is caused by
contact.
Autora: Marta García T.Autora: Marta García T.
35. Nastic Movements: are temporary responses
of particular parts of a plant to external
stimuli.
Autora: Marta García T.Autora: Marta García T.

37. Plants are autotrophs: they make their own food (glucose)
through a process called Photosynthesis.
Photosynthesis is the process in which the plant
transform inorganic matter into organic matter, using
the the energy from sunlight.
In this process, the plant requires carbon dioxide, and
produce oxygen, which is released to the atmosphere.
Water + Mineral Salts + CO2 + Sunlight O2 + Glucose
40. HOW DOES PHOTOSYNTHESIS OCCUR?
Water and mineral salts are absorbed by the roots,
using the root hairs.
This mixture of Water with mineral salts dissolved
is called “Raw Sap).
41. The raw sap travels up the stem to the leaves
through special vessels called “Xylem”.
42.
43.
44. Leaves cells contain a pigment called Chlorophyll,
which absorbs the sunlight.
Chlorophyll is inside special organelles called
Chloroplasts.
45. At the same time, leaves absorb carbon dioxide
through a pores calle Stomata (estomas).
46.
47. In the leaves, raw sap and carbon dioxide react
using the solar energy, and glucose, water and
oxygen are produced.
Water + Mineral Salts + CO2 + Sunlight O2 + Glucose
48. Oxygen is released to the atmosphere.
Elaborated Sap (glucose disolved in water) is
distributed to all the plant cells using the Phloem
Vessels.
