Question

How is excretion in plants different from excretion in animals?

Answer 1

Plants do not have specialised structures like nephrons for excretion of wastes. Oxygen, which is a waste product of photosynthesis, and carbon dioxide, which is a waste product of respiration, diffuse out through the stomata in leaves and lenticels in stems.


Components of this system in vertebrates include the kidneys, liver, lungs, and skin. Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane. Elimination is the removal of feces.

Answer 2

Answer:

Unlike animals, plants do not have specialised excretory organs. Excess carbon dioxide and oxygen are excreted from the plant through the stomata in the leaves.
