question 96
when light shines on one side of a plant more than another, auxin becomes concentrated on ____.
a the shady side
b throughout the plant equally
c the sunny side

Explanation:

In plant phototropism, auxin (a plant hormone) moves to the shady side when light is unevenly distributed. This causes the shady - side cells to elongate more, making the plant bend towards the light. Option B is incorrect as auxin isn't distributed equally in this situation. Option C is incorrect because auxin doesn't concentrate on the sunny side; it moves to the shady side.

Answer:

A. the shady side
