Plants and Photosynthesis
Plants and Photosynthesis
Photosynthesis - The process of plants turning sunlight into energy.
Stomata - The small pore in the epidermis of a plant.
Osmosis - Movement of particles from an area of low concentration to an area of high concentration through a semi-permeable membrane.
Flowering - Sexual plant reproduction
Pollination - Process of pollen from one plant getting stuck to another through wind, animals and in some rare cases water.
Fertilization - The procedure of the nuclei of an egg cell and a sperm cell fusing together.
Seed production - The production of seeds subsequent to fertilization which makes the ovary the fruit.
Seed dispersal - When the plant disposes of it's seeds so there is no fight for resources.
Diffusion - The way in which Carbon Dioxide gets into the leaf. / When the kinetic energy in the water increases and the particles move around more.
Guard cells - Open and close the stomata.
Chlorophyll - Pigment that makes leaf green and is the sit of photosynthesis.
Transpiration - The movement of water through plants and its evaporation from aerial parts, such as leaves and stems.
Receptacle - Flattened head of steam where flower rests.
Sepals - Green leaf that protects the bud.
Petals - Attracts insects by being brightly coloured, large, scented and contain nectar.
Stamens - Is a male part and contains Anthers, which produce pollen and the filaments which help to support the anthers.
Carpel - Female part, contains stigma, this has a sticky surface to collect pollen from insects, style, is a tube that conjoins the stigma to the ovary and the ovary this part contains the female gamete.
All necessary for a living organism
Is made from cellulose. Protects and supports the cell.
- Allows things to enter and exit the cell.
- Chemical reactions occur here.
- Area of storage
- Contains the green pigment chlorophyll which is responsible for photosynthesis.
- Contains the DNA of the plant which instructs the production of protein.
- Site of respiration
- Storage carbohydrate of a plant.
Testing a leaf for starch
Showing that Carbon Dioxide is necessary for photosynthesis.
Showing that light is necessary for photosynthesis
Measuring the rate of photosynthesis
- To suck up the Carbon Dioxide and light to help Photosynthesis occur.
- Is there to provide support for the leaves, buds and branches. Also helps to spread out leaves for maximal light absorption.
- Is there to draw in water and minerals from the ground.
Photosynthesis -Carbon Dioxide + Water >>>>> Glucose + Oxygen
Respiration - Glucose + Oxygen >>>>> Carbon Dioxide + Water
Root hair cells
Adapted for absorption. It has a large SA which helps it to take in a lot of water and minerals. A narrow cell wall helps water pass through it quickly and easily.
