Question

In plants, gaseous exchange occurs through the process of:

• A. Diffusion
• B. Osmosis
• C. Active transport
• D. None of the above

Answer 1

The correct option is A Diffusion

Plants obtain the gases they need through their leaves. They require oxygen for respiration and carbon dioxide for photosynthesis. These gases diffuse into the intercellular spaces of the leaf through pores, which are normally on the underside of the leaf and are called stomata.
