Photosynthesis and Respiration Are Linked, Not Opposed
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Photosynthesis consumes carbon dioxide and releases oxygen; respiration consumes oxygen and releases carbon dioxide — each process's output is the other's raw material.
Show
Oxygen released by a plant's photosynthesis can be taken up by that plant's own mitochondria, or by any nearby aerobic organism.
Watch for
Neither process's byproduct is waste — each is a substrate the other pathway depends on.
