Question

why do endocytosis found in animals only ?

Answer 1

endocytosis is not found in plants because of the rigid cell wall present over cell membrane. Thus it is present in animals only.

Answer 2

Answer:

Endocytosis is swallowing up of food and other substances from external medium by the plasma membrane. This is possible only when plasma membrane is in direct contact with external medium. It occurs only in animal cells. In plant cells, a cell wall is present on the plasma membrane. Therefore, their plasma membrane cannot perform endocytosis.
