Plant Excretion and Waste Management

The video explains how plants excrete waste, similar to animals but through different methods. Plants eliminate gaseous waste like carbon dioxide and oxygen through stomata. Excess water is lost via transpiration. Plants store waste in leaves and fruits, which are shed when ripe. Some plant wastes, like latex and resin, are valuable to humans. The video concludes with a summary of these excretion methods.

How do plants differ from animals in terms of waste elimination?

• Plants do not produce any waste.

• Plants use kidneys to filter waste.

• Plants eliminate waste through stomata.

• Plants urinate like animals.

What is the role of stomata in plant excretion?

• They store waste products.

• They release oxygen and carbon dioxide.

• They absorb nutrients.

• They produce energy.
