Question

Epidermal cells containing chloroplasts are

• A. Hydathodes
• B. Accessory cells
• C. Stomata
• D. Guard cells

Answer 1

The correct option is D Guard cells

Stomata are small openings on the leaves which helps in transpiration and gaseous exchange. The cells of stomata are known as guard cell. The guard cells contain chloroplasts, so they can manufacture food by photosynthesis. Due to the presence of chloroplast, guard cell synthesizes glucose and so its osmotic potential increases and it withdraws water from the epidermal cell and turns turgid and the stomata open.

So, the correct answer is option D.
