Question

The transport of oxygen and carbon dioxide in the cell takes place by which process?

• A. Diffusion
• B. Imbibition
• C. Osmosis
• D. Plasmolysis

Answer 1

The correct option is A

Diffusion

Transport of gases takes place by diffusion inside the cells. When oxygen-rich blood reaches the cells, oxygen which is in higher concentration in the blood diffuses into the region of low concentration i.e., inside the cell. Simultaneously, carbon dioxide, which is in higher concentration inside the cell, diffuses into the blood.
