Answer 1

The correct response is:

Roots are underground and are not exposed to sunlight.

Chloroplasts are the organelles responsible for photosynthesis, which requires sunlight. Since root cells are located underground, they do not receive light, and therefore do not need chloroplasts. Instead, they focus on nutrient and water absorption.
