Question

Which of the following is a method by which plants excrete wastes?

• A. Transpiration
• B. Lost as leaves
• C. Photosynthesis
• D. All of the above

Answer 1

The correct option is D

All of the above

Plants lose water in the process of transpiration. Plants use the fact that most of their cells are dead cell and store their wastes in leaves. These wastes are lost when they lose these leaves. Oxygen produced during photosynthesis passes out through the stomata. Therefore, all 1, 2 and 3 are the methods by which plants excrete waste.
