Large complexes of proteins and pigments (light-absorbing molecules) that are optimized to harvest light are called:

Photosystems

During the dark reactions, atmospheric carbon dioxide (CO2) is brought into the leaf through tiny pores called: ___________

Stomata

CO2 is converted into a stable organic compound through a process known as

Carbon fixation

Photosynthesis is a catabolic process.

false
