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

Question

Quizplus · Accepted Answer

Moving chloroplasts to the sunny side of each cell maximizes light absorption, which is essential for photosynthesis. This increases the plant's ability to produce energy and grow, giving it a clear adaptive advantage. Options B, C, and D are not related to the movement of chloroplasts in response to blue light.
