1. What is excretion in plants?
Ans. Excretion in plants refers to the process by which plants eliminate waste products or harmful substances from their cells. This process is essential for maintaining the overall health and functioning of the plant.
2. How do plants excrete waste?
Ans. Plants primarily excrete waste through the process of transpiration. Transpiration is the loss of water vapor through the stomata, which are tiny openings on the surface of the leaves. Along with water vapor, plants also excrete waste substances, such as oxygen and metabolic by-products, through this process.
3. What are the waste products excreted by plants?

4. How does excretion help plants maintain their internal balance?
Ans. Excretion plays a crucial role in maintaining the internal balance of plants. By eliminating waste products and harmful substances, plants prevent the accumulation of toxins and maintain appropriate levels of essential nutrients and gases. This helps in ensuring optimal growth and functioning of plant cells and tissues.
5. Can plants excrete excess water?
