Question

During high light intensity, the chloroplasts align themselves

• A. In vertical position along lateral walls
• B. Along tangential walls
• C. In centre and get scattered
• D. Perpendicular to light

Answer 1

The correct option is A In vertical position along lateral walls

During high light intensity, the chloroplasts aligned themselves perpendicular to light to avoid photooxidation. In photooxidation firstly decreases the rate of photosynthesis and further disintegrated the chloroplast due to the high intensity of light.

So the correct option is 'perpendicular to light'.
