Excretion In Plants : Notes on Biology For Class 10th


      • 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:

    • The gaseous wastes, oxygen, carbon dioxide and water vapor are removed through the stomata of leaves and lenticels of stems.
    • Some waste products collect in the leaves and bark of trees.
    • When the leaves and bark are shed, the wastes are eliminated
