Question

Why is endocytosis found in animals only?

Answer 1

Explanation:

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.

Answer 2

Answer:

For endocytosis to occur, the outermost membrane should be flexible but in plant cells cell wall is the outermost membrane which is very rigid hence no endocytosis occurs.
