In which plant tissue does photosynthesis primarily occur?
Correct answer: A. Mesophyll
- A. Mesophyll
- B. Epidermis
- C. Cortex
- D. Xylem
Explanation
Photosynthesis primarily occurs in the mesophyll tissue of plant leaves. The mesophyll tissue is specialized for photosynthesis and is located between the upper and lower epidermis of the leaf. It contains chloroplasts, the organelles responsible for capturing sunlight and carrying out photosynthesis. The mesophyll tissue consists of two main types: the palisade mesophyll, which is closely packed with elongated cells, and the spongy mesophyll, which has loosely arranged cells with air spaces for gas exchange.

About Respiration
The human respiratory system includes the air passages, lungs, alveoli and breathing muscles, while gaseous exchange explains how oxygen enters blood and carbon dioxide leaves it by diffusion. The effects of smoking include damage to cilia and alveoli, reduced gas exchange, chronic bronchitis, emphysema and increased risk of lung cancer.
