Detailed Solution

Excretion in plants is useful to humans because many waste products released by plants, like gums, resins, latex, and oxygen, have medical, industrial, and environmental benefits.

Just like animals, plants also produce waste materials during life processes such as photosynthesis and respiration. However, plants have no special organs for excretion. They remove waste through simple natural processes like transpiration, diffusion, and secretion of useful by-products.

Ways Plants Excrete Waste

Through Stomata: Excess water is removed by transpiration.
Through Leaves: Plants shed old leaves to remove stored wastes.
Through Roots: Some wastes are released into the soil.
By Secretion: Wastes like resins, gums, and latex are stored in special cells and later secreted.

How This Helps Humans

Plant Waste Product	Use for Humans
Oxygen	Essential for human respiration
Gums and Resins	Used in medicines and adhesives
Latex	Used to make rubber products
Essential Oils	Used in perfumes and aromatherapy
Tannins	Used in leather industry

Thus, plant excretion not only maintains plant health but also supports human life through useful by-products and oxygen release.
