Question

When are chloroplasts aligned perpendicular to radial walls?
(A) At low light intensity
(B) At high light intensity
(C) In absence of Light
(D) A and B​

Answer 1

Answer:

At the time of lower / optimum light incidents or under stress conditions the chloroplasts will be aligned with their flat surfaces parallel to the walls of mesophyll cells so that they can get the maximum amount of light . And when the incident light will be of very higher light intensities then the chloroplasts will be aligned perpendicular to the wall to avoid photooxidation .

Explanation:

Pls mark me a brainliest

Answer 2

option B is correct because at high light intensity choloroplast aligned perpendicular to radial walls to avoid photoxidarion.
