Photosynthesis is used to produce food for plants in the form of glucose. in the process, oxygen is released. as shown in the diagram, plants require water and carbon dioxide (from the air). what else is required for photosynthesis and what role does it play?

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
