1
Q

A
Light energy
2
Q
What materials do green plants and algae need to make their food
A
Soil and oxygen
3
Q
What happens during photosynthesis
A
Light energy absorbed by chlorophyll-found in chloroplast- in some plant cells and algae
This energy is used to convert co2 and water into glucose
Oxygen released as by-product
4
Q
What factors limit the rate of photosynthesis
A
Shortage of light
Low temp
Shortage of co2
5
Q
What do plants use glucose for in photosynthesis
A
Starch to store energy Reparation for when there is no light Proteins Fat or oils in seeds Produce cellulose to strengthen cell wall
