Solution: Upon exposure to blue light, plants not only begin to grow toward the light, but move their chloroplasts to the sunny side of each cell. The adaptive advantage of moving chloroplasts to the sunny side of each cell ________. a. maximizes light absorption by the chloroplasts for photosynthesis b. increases production of phototropic hormones c. maximizes heat absorption by the chloroplasts for cellular respiration d. increases adenosine triphosphate (ATP) production during the light-independent reactions
