Definitions:

Proton Gradient

The gradient of hydrogen ions (protons) across a membrane, which is a form of potential energy used for ATP production in cells.

Photosynthesis

The process by which green plants, algae, and some bacteria transform light energy into chemical energy stored in glucose, using carbon dioxide and water and releasing oxygen as a byproduct.

Stomata

Small pores located in the epidermis of plants that provide for gas exchange for photosynthesis; each stoma is flanked by two guard cells, which are responsible for its opening and closing.

Gas Exchange

The biological process through which different gases are transferred in opposite directions across a surface.
