BIOLOGY

The food made from photosynthesis is used...

1. To release energy for cells to be active
2. In the leaves to make new cells
3. Stored in the leaf as starch
4. Sent through the veins to parts of the plant that cannot carry out photosynthesis.

if starch is present in the leaf, iodine would change from orange to blue/black

4 factors which affect photosynthesis:
1. Carbon dioxide
2. water
3. light
4. temperature
