Key concepts

3 concepts

  1. 1

    The reactants (inputs) of photosynthesis are included in the products (outputs) of cellular respiration, and the products (outputs) of photosynthesis are included in the reactants (inputs) of cellular respiration.

  2. 2

    The two major reactions that occur in the chloroplast that, together, make up photosynthesis are the light dependent reactions and the light independent reactions.

  3. 3

    In CAM photosynthesis, plants open their stomata at night to capture carbon dioxide and chemically store it, then use it the next day when the sun is shining but their stomata are closed.
