Question

Green pigment is found

• A. In roots.
• B. In leaves.
• C. In stem
• D. All of the above.

Answer 1

The correct option is B In leaves.

Chloroplasts are the tiny structures in plant cells where photosynthesis happens. Chloroplasts contain chlorophyll, a green pigment that absorbs light energy for photosynthesis. However, chloroplasts are not found in all plant cells. For example, they are not found in root hair cells. These cells absorb the water needed by the plant for photosynthesis. However, since they are usually underground and in the dark, they are unable to photosynthesise anyway. Leaves contain many cells with chloroplasts. Leaves are often broad so that they have a large surface area to absorb sunlight. Broader leaves enable more sunlight to be absorbed. Green pigment is absent in roots and stem.

Therefore, the correct answer is option B.
