Photosynthesis
Plants and algae are the main producers of food, which they synthesis from sunlight in a process called photosynthesis. They are also therefore the primary producers of biomass in all food webs and food chains.
-
There are three different factors that can affect the rate of photosynthesis: Temperature, Light Intensity and Carbon Dioxide Concentration.
Structure Adaptions
Root Hair Cells - Specialised to take up water by osmosis and mineral ions by active transport from the soil as they are found in the tips of roots.
Xylem Cells - Specialised to transport water and mineral ions up the plant from the roots to the shoots.
Phloem Cells - Specialised to carry the products of photosynthesis (food) to all parts of the plants.
-
Translocation
Translocation is the movement of food substances (such as sucrose) made in the leaves up or down the phloem, for use immediately or storage.
