Question

Waste product produced during respiration in plant are

• A. $C{O}_2$
• B. Water
• C. Oxygen
• D. Both A and B

Answer 1

The correct option is D Both A and B

Plants produce carbon dioxide and water as respiratory waste products. In green plants, the carbon dioxide released during respiration gets utilised during photosynthesis. Oxygen is a waste product generated during photosynthesis and exits through stomata, root cell walls, and other routes. Plants can get rid of excess water by transpiration and guttation.

So, the correct answer is option D.
