Question

why endocytosis found only in animal cell

Answer 1

Answer:

Since plant cells have a cell wall covering around their cell membrane, endocytosis is not possible. It is used by animal cells because most substances important to them are large polar molecules, and thus, cannot pass through the plasma membrane.

Answer 2

Answer:

Endocytosis generally occurs in animal cells and very rarely in plant cells as the cell membrane in plant cell is surrounded by a rigid cell wall. Cell wall causes hindrance in the invagination of plasma membrane which forms the transport vesicles for the transfer of substances in the cytoplasm of the cell. Nitrogen fixing bacteria enter the root cells in legumes through endocytosis.
