Question

Waste product/s produced by plants is/are

• A. Carbon dioxide
• B. Water
• C. Oxygen
• D. All of these

Answer 1

The correct option is D

All of these

Plants use different methods to excrete substances than those in animals. Oxygen is considered to be waste product in plants. They get rid of excess water by the process of transpiration. For other wastes, plants use the fact that many of their tissues consist of dead cells, and that they even lose some parts like leaves. Other waste products are stored as resins and gums, especially in old xylem. Plants also excrete some waste substances into the soil around them. When plants respire, plants produce carbon dioxide and this excess carbon dioxide must be eliminated. Hence the waste products in plants are oxygen, carbon dioxide and water.
