Question

Which is true for both photosynthesis and cellular respiration? A. They require oxygen as a reactant. B. They require organelles. C. They require light energy from the Sun. D. They require cells to use water.

Answer 1

B

Step-by-step explanation:

Photosynthesis and cellular respiration are opposite processes, so a reactant of one would be the product of the other and vice versa. This means that A, C, and D are false because they don't apply to both processes. B is true because photosynthesis requires chloroplasts and cellular respiration requires mitochondria to occur.
