Learning Objective
I can describe how photosynthesis converts light energy into chemical energy.
- 1
The reactants (inputs) of photosynthesis are carbon dioxide and water, while the products (outputs) are glucose and oxygen.
- 2
Chlorophyll is a pigment found in chloroplasts that captures light for photosynthesis, absorbing red and blue light, and reflecting green light.
- 3
The two major reactions of photosynthesis are the light-dependent reactions which occur in the thylakoids, and the light-independent reactions (Calvin Cycle) which occur in the stroma.
