Key concepts

3 concepts

  1. 1

    The reactants (inputs) of photosynthesis are carbon dioxide and water, while the products (outputs) are glucose and oxygen.

  2. 2

    Chlorophyll is a pigment found in chloroplasts that captures light for photosynthesis, absorbing red and blue light, and reflecting green light.

  3. 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.
