Question

Assertion: Phototropism in plants is caused
by auxin
Reason: The plant showing bending has more elongated
cells on the illuminated
side.
​

Answer 1

Answer:

Both assertion and reason are true

Explanation:

Phototropism is the growth of an organism in response to a light stimulus. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light.
