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) maximises light absorption by the chloroplasts for photosynthesis
B) increases production of phototropic hormones
C) maximises heat absorption by the chloroplasts for cellular respiration
D) increases adenosine triphosphate (ATP) production during the light-independent reactions

Question

Quizplus · Accepted Answer

When chloroplasts are moved to the sunny side of each cell, they can maximise light absorption, which is used for photosynthesis. This adaptive advantage allows the plant to produce more food, which can aid in growth and reproduction.
