Lesson 1 nutrition in plants
Nutrition in plants can occur through two main modes: autotrophic and heterotrophic nutrition. Autotrophic nutrition involves plants producing their own food through the process of photosynthesis using carbon dioxide, water and sunlight. Heterotrophic nutrition involves plants that cannot produce their own food and instead rely on other organisms for nutrition, such as parasitic plants that derive nutrients from a host plant, or saprotrophic fungi that break down dead and decaying matter.
Nutrition in Plants
Plants obtain nutrition through various modes including autotrophic, heterotrophic, and saprotrophic nutrition. Autotrophic nutrition, which is found in green plants, involves plants making their own food through photosynthesis. During photosynthesis, green plants such as leaves use carbon dioxide, water, and sunlight to produce carbohydrates and release oxygen. Some non-green plants rely on heterotrophic nutrition and obtain nutrients from other living organisms. Saprotrophic plants get nutrients from decaying organic matter. Symbiotic relationships also provide nutrition, such as rhizobium bacteria living in root nodules of legumes that provide nitrogen to the plant in exchange for shelter and food.
Nutrition in Plants
This document discusses nutrition in plants. It explains that plants get nutrients from the soil and light energy from the sun to produce their own food through photosynthesis. There are different modes of nutrition in plants - autotrophs can produce their own food, heterotrophs obtain food from other organisms, and some plants have parasitic or symbiotic relationships. The document also describes two activities - one showing that sunlight is necessary for photosynthesis, and another observing the fungus bread mould growing on bread as an example of a saprotroph.

Plants obtain their nutrition through autotrophic nutrition, also called photosynthesis. During photosynthesis, plants use energy from sunlight, carbon dioxide from the air, and water to produce glucose and release oxygen. Animals obtain nutrition through heterotrophic nutrition, either holozoic where they feed on other organisms, saprophytic where they feed on dead and decaying matter, or parasitic where they live in or on a host organism.
Heterotrophic nutrition
The document summarizes the four types of heterotrophic plants: parasitic plants absorb food from other host plants, saprophytic plants derive nutrients from decaying material, insectivorous plants trap and consume insects to gain nutrients, and symbiotic plants live in association with other species and share food resources mutually.

How do plants grow
Non-vascular plants like mosses do not have true roots, stems, or leaves because they lack vascular tissue. Vascular plants contain two types of vascular tissue - xylem and phloem. Xylem transports water and minerals from the roots to the leaves, while phloem transports food from the leaves to all parts. Vascular plants include everything from tiny duckweed to giant redwood trees. They have roots that absorb water and nutrients, stems that transport resources, and leaves containing chloroplasts for photosynthesis.
Earland Plant Evolution Trends
The document discusses evolutionary trends in plants, including their transition from aquatic to terrestrial environments. Early plants included bryophytes. Later plants evolved vascular tissue to transport water and nutrients, a waxy cuticle to prevent water loss, and stomata to regulate gas exchange. Seed plants further evolved seeds and pollen for protection and dispersal of reproductive cells on land. Throughout plant evolution, the sporophyte generation became larger and more prominent than the gametophyte generation.
Sexual reproduction in plants
This document discusses sexual reproduction in plants. It describes self-pollination which occurs when a flower has both male and female parts and pollen from the male parts contacts the female parts. Cross-pollination transfers pollen between male and female parts of different plants, increasing genetic diversity. Common agents of pollination include wind, water, and insects. After fertilization, the zygote divides within the ovule to form an embryo, and the ovule develops a seed coat and becomes a seed within a ripening fruit.
Plant transport
Plant transport systems include xylem and phloem. Xylem transports water and minerals upwards from roots to shoots passively, using no energy. Phloem transports food such as sucrose horizontally throughout the plant using energy from ATP. Xylem vessels are located towards the edges of stems to resist bending forces, while located centrally in roots to withstand stretching. Transpiration is the evaporation of water from plant leaves, powered by the transpiration stream which replaces lost water. Transpiration cools plants and transports minerals upwards from roots.
Sexual reproduction in plants
The document outlines the process of sexual reproduction in flowering plants, including the structure and function of floral parts, pollination, fertilization, seed formation, dispersal, dormancy, and germination. Key points include that pollen grains produce male gametes, the embryo sac produces an egg cell and polar nuclei, double fertilization occurs, seeds vary in structure depending on whether they are endospermic or non-endospermic, and seeds require specific conditions like water and oxygen to successfully germinate.
PLANT TISSUES PRESENTATION
Plant tissues can be classified as meristematic or permanent tissues. Meristematic tissues are actively dividing cells responsible for plant growth located in apical, lateral, and intercalary meristems. Permanent tissues stop dividing and perform specific functions. Plant tissues include dermal tissues like epidermis and periderm, ground tissues like parenchyma and sclerenchyma, and vascular tissues that transport water and nutrients throughout the plant like xylem and phloem. Shoot and root systems are interdependent with shoots producing sugars and roots absorbing water and minerals.
Plant tissues
The document summarizes plant tissues and structures. It describes the basic tissues of plants including meristematic tissues that produce new growth, simple tissues like parenchyma and sclerenchyma, and complex tissues like xylem and phloem. It also discusses the shoot and root systems of angiosperms as well as leaf structures and functions. Secondary growth in woody plants is briefly covered.
Reproduction in plants
This document summarizes sexual and asexual reproduction in plants. Sexual reproduction involves two parents fusing gametes to produce offspring that differ from the parents, while asexual reproduction uses one parent to produce identical offspring through budding, stolons, or runners. The document then discusses pollination, fertilization, seed structure, and dispersal methods like wind or animal vectors.
Plant reproduction
Plant reproduction involves the transfer of pollen from the anther to the stigma, known as pollination. This can occur through wind or animal vectors. Fertilization happens when the pollen tube delivers sperm to fertilize the ovule. The ovary then develops into a fruit containing seeds. Seeds are dispersed by various mechanisms like wind, water, or animals to colonize new areas away from the parent plant. Germination starts when the seed takes in water, activating enzymes to break down food stores that fuel embryo growth into a new plant.
Classification of plants
The document classifies plants into two main categories: flowering plants and non-flowering plants. Non-flowering plants include mosses and ferns. Mosses do not have true roots or vascular tissues, reproduce via spores, and prefer damp environments. Ferns have roots, leaves, underground stems and vascular tissues, reproduce via spore-producing organs on their leaves, and prefer damp shady places. Flowering plants are further divided into gymnosperms like pine trees, which have needle-shaped leaves and bear naked seeds in cones, and angiosperms which have true flowers and fruits containing seeds. Angiosperms include monocots and dicots, distinguished by whether they have one or two seed leaves and
Experimental techniques
This document discusses various techniques for purifying substances, including filtration, crystallization, distillation, and chromatography. It provides examples of how each technique works and the types of mixtures it can be used to separate. Key points include:
- Filtration separates insoluble solids from liquids by passing the mixture through a filter paper.
- Crystallization forms pure crystals of a soluble solid by slowly evaporating the solvent from a saturated solution.
- Distillation boils a liquid mixture and condenses the vapor to separate components with different boiling points.
- Chromatography separates mixtures by exploiting differences in how substances partition between a stationary and mobile phase.

- Chromatography separates mixtures by exploiting differences in how substances partition between a stationary and mobile phase.
Chromatography windows 8
Chromatography is a technique used to separate mixtures of substances that are soluble in the same solvent. A spot of the mixture is placed on filter paper and a solvent is used to carry the different substances along the paper at different rates, based on how strongly they interact with the solvent and paper. This allows the different substances to be visually identified based on how far they travel up the paper compared to samples of single known substances run alongside the mixture.
Scientific enquiry
The scientific method involves 6 key steps: 1) making observations and recording them, 2) asking a question and developing a testable hypothesis, 3) conducting research, 4) performing an experiment, 5) recording results, and 6) drawing a conclusion about whether the hypothesis was confirmed or not. The document then discusses the concept of variables in an experiment, defining the independent variable as the factor that is deliberately changed, the dependent variable as the factor that is measured, and controlled variables as other factors kept the same.
Lab safety rules, safety symbols and tools
This document provides information about lab safety rules, common safety symbols seen in laboratories, and descriptions of various laboratory tools and equipment. It lists 10 lab safety rules but does not specify them. It also describes safety symbols for substances that are explosive, flammable, corrosive, toxic, radioactive, pose environmental dangers, or are oxidizing, gases under pressure, or health hazards. Finally, it provides the names, uses, and simple diagrams of common lab tools including test tubes, beakers, conical flasks, Bunsen burners, tripods and gauzes, clamps and stands, funnels and filter paper, round-bottom and flat-bottom flasks, separating funnels, and delivery tubes.

Electric circuits 1
The document discusses electric circuits and their components. It explains that an electric circuit requires a power source, conducting materials like wires, components that use the electricity such as light bulbs, and switches. It also describes how to draw circuit diagrams using symbols and discusses key circuit concepts like current, voltage, resistance, and Ohm's law. Ohm's law defines the relationship between current, voltage, and resistance in a circuit. The document uses examples like dimmer switches and defibrillators to illustrate these circuit principles.
Plants life cycles
1. Seeds need certain conditions like water, light, and warmth to germinate and grow into new plants.
2. Flowers have both male and female parts that work together to create new plants through pollination and fertilization. Pollen is transferred by insects from the male stamen to the female stigma and ovary.
3. The process of reproduction through spreading seeds and pollinating flowers is important for the circle of life as it allows plants and animals to continue their species and prevent extinction.

Plants undergo photosynthesis to produce their own food. Photosynthesis requires carbon dioxide, water, sunlight, and chlorophyll. It occurs in the leaves of plants, specifically in the chloroplasts of leaf cells. The process produces glucose and oxygen and provides plants with the energy and nutrients they need to grow.
25 people and the planet part1
Hunter-gatherers lived in East Africa about 200,000 years ago and gradually spread across continents. Around 10,000 years ago, some groups in the Middle East began farming, which allowed population growth and specialization in crafts. Early machines like watermills and windmills harnessed energy from water and wind. The steam engine was invented in the 18th century and powered the Industrial Revolution, but also caused pollution. Today various renewable and non-renewable sources provide energy for transportation, electricity generation, and more.

26 people and planet part 2
This document summarizes several ways that human activities have impacted the environment. It discusses how the development of farming, industry, and fossil fuel use has destroyed natural habitats and introduced chemicals like pesticides and pollutants. It also describes how the introduction of gases like CFCs in the early 20th century were found to be damaging the ozone layer. The extra carbon dioxide from burning fossil fuels may cause global warming and changes to habitats worldwide. Acid rain can damage soil and kill plants from gases emitted by volcanoes, lightning, power stations, and factories.
Heat transfer
Heat can be transferred through three main processes: conduction, convection and radiation. Radiation involves the transfer of heat energy through electromagnetic waves called infrared radiation. Infrared radiation is able to travel through empty space, which is how heat from the Sun travels to the Earth. All objects emit infrared radiation, with the amount emitted depending on the object's surface properties - matte black surfaces are the best emitters and absorbers of infrared radiation.
Static electricity
Static charge builds up when two insulating materials are rubbed together through friction, such as a plastic comb moving through hair. This friction causes electrons to be transferred from one material to the other, leaving one material with an excess of electrons and an overall negative charge, and the other material with a deficit of electrons and an overall positive charge. Static charge comes from the transfer of electrons between atoms during rubbing, as electrons can sometimes be removed from their atoms.
Week 7 10 turning effects
This document discusses balanced and unbalanced forces. It defines a moment as a turning effect caused by a force, and explains that the size of a moment depends on two factors: the size of the force and the perpendicular distance from the pivot point. It provides the moment equation and gives examples of moments, including a see-saw. It introduces the principle of moments, which states that for an object to be balanced, the sum of clockwise moments must equal the sum of anticlockwise moments. Finally, it defines the center of mass as the point where all the mass of an object seems to be concentrated.
9.10.3 pressure
This document discusses the concept of pressure in physics. It defines pressure as the force applied over an area, and provides an example comparing the pressure exerted by a fingertip versus a palm. Pressure is measured in units of pascals or other derivatives of newtons per area. The document explains that applying the same force over a larger area results in lower pressure. It provides examples of how high and low pressure are used in different situations like shoes on muddy ground, skis on snow, and knives cutting food. Finally, it briefly discusses how pressure increases with depth in liquids and can be transmitted through a liquid.
Density
1. Density is defined as mass per unit volume and can be used to compare how much mass is contained within a certain volume of different materials.
2. The density of a material can be calculated by measuring its mass and volume, with density equaling mass divided by volume.
3. There are different methods to determine the density of regular solids, irregular solids, liquids, and gases depending on whether their volume needs to be measured directly or determined through displacement.
Ch.16.magnets and electromagnets
The document discusses magnetism and electromagnets. It begins by identifying which materials are magnetic, such as iron, nickel, and cobalt. It then explains what magnetic fields are, how they can be visualized using iron filings, and how their patterns differ depending on whether two magnets' north or north/south poles are brought together. The document also explores how electromagnets work and can be made stronger by increasing the number of coils or electrical current. Electromagnets have advantages over permanent magnets in applications like recycling plants due to being able to be turned on and off.
7 l the_solar_system_and_beyond
Scientists' ideas about the solar system have developed over time from ancient Greek philosophers like Aristotle and Ptolemy, who believed the Earth was the center, to Copernicus, who proposed the Sun was the center in the 16th century. Kepler later suggested elliptical orbits and Newton developed the law of universal gravitation. In the 18th-19th centuries, Herschel discovered Uranus and Hubble showed the universe is expanding, leading to the Big Bang theory. Major advances were made through improved telescope technology by Galileo and others.
