Plants have no special organs for removal of wastes. The waste products of respiration and photosynthesis are used as raw materials for each other. Oxygen gas produced as a by-product of photosynthesis is used up during respiration and carbon dioxide produced during respiration is used up during photosynthesis.
Excretion is carried out in the plants in the following ways:
1. The gaseous wastes, oxygen, carbon dioxide and water vapour are removed through stomata of leaves and lenticels of stems.
2. Some waste products collect in the leaves and bark of trees. When the leaves and bark are shed, the wastes are eliminated.
3. Some waste products are rendered harmless and then stored in the plant body as solid bodies. Raphides, tannins, resins, gum, rubber and essential oils are some such wastes.

There are many ways in which plants can excrete:
1.O2 is also the excretory product of plants
2. Plants lose water by transpiration.
3. Plants also excrete by removing waste material in soil around them.
4. Oil, Gums and resins are also waste products of plants.
5. Plants also store their waste materials in old xylem.
6. They also store their waste materials in leaves and then leaves fall off.
