How do leaves of plants help in excretion?

How do leaves of plants help in excretion? Explain briefly.

Answer 1

Leaves play an important role in excretion in plants because CO₂ is expelled out through pores of stomata present in the leaf. Plants shed leaves to get rid of excretory products deposited on them. 

Answer 2

1. Plants use guttation and transpiration to eliminate extra water.
2. The stomata on leaves aid in the excretion of carbon dioxide and oxygen, which are waste products of respiration and photosynthesis, respectively.
3. Through a process called abscission, which causes leaves to fall off and turn yellow, leaves aid in excretion. Plants use this technique to eliminate poisons and other pollutants.
