What happens during photosynthesis?
light energy is transferred to chemical energy.
1 of 10
What part of the plant is well adapted for photosynthesis?
The leaves
2 of 10
What is the word equation for photosynthesis?
carbon dioxide+water -----> light energy = glucose+ oxygen
3 of 10
What can photosynthesis only be carried out by?
green plants and algae
4 of 10
what does chlorophyll in the chloroplasts do?
absorbs the suns light energy
5 of 10
What are the three stages in the process of photosynthesis?
1) Carbon dioxide is taken in by the leaves, and water is taken up by the roots 2) The chlorophyll traps the light energy needed for photosynthesis 3) This energy is used to convert the carbon dioxide and water into..
6 of 10
continued...
...glucose (a sugar)
7 of 10
what happens to oxygen during this process?
released as a by-product of photosynthesis.
8 of 10
what happens to some of the glucose?
converted into insoluble starch for storage.
9 of 10
How can we test for starch in leaves?
the iodine test- we can show that photosynthesis has occured. green(with chlorophyll) white (without) Only the green will turn the iodine blue/black to show there is starch.
