What is released as a byproduct of photosynthesis?
Definition
oxygen
Term
Which best describes light-independent reactions?
Definition
They utilize the energy stored in ATP and NADPH.

Term
What is cholorophyll?
Definition
A green substance that absorbs sunlight and makes the energy from sunlight available for chemical reactions.
Term
Where is the chlorophyll located in plants?
Definition
In the chloroplasts of plant cells
Term
What plants do not use photosynthesis?
Definition
Plants that are out of reach of sunlight, for example seaweed.
Term
How does chlorophyll work during photosynthesis?
Definition
It absorbs sunlight to make energy for chemical reactions.
Term
What are the products of photosynthesis?
Definition
Oxygen and glucose
Term
Why do plants need photosynthesis?
Definition
to make food to build new cells and tissues to grow
Term
If there was no photosynthesis what would happen?
Definition
there would be no oxygen for humans and animals and there would an excess amount of carbon dioxide.
