Question

In a chloroplast, which of the following sites trap solar energy?

• A. Thylakoid membranes
• B. Stroma
• C. Outer membrane
• D. Inner membrane

Hint:

Thylakoid membranes in chloroplasts are the primary sites where light energy is captured during photosynthesis.

Answer 1

The Correct Option is A

1. Structure of chloroplast:
Chloroplasts contain stacked membranous structures called thylakoids, which are arranged in stacks known as grana, surrounded by stroma. 2. Site of solar energy trapping:
The thylakoid membranes contain chlorophyll and other pigments that absorb solar energy for photosynthesis. 3. Role in photosynthesis:
The absorbed light energy is used to drive the light-dependent reactions of photosynthesis occurring in the thylakoid membranes.
