Question 33
Why is endocytosis found in animals only?
Endocytosis is a mechanism by which a living cell engulfs any matter into its cytoplasm by invaginating its plasma membrane and forming a vacuole.
Endocytosis generally occurs in animal cells and very rarely in plant cells as the cell membrane of plant cells are surrounded by a rigid cell wall. The cell wall causes a hindrance in the invagination of the plasma membrane which forms the transport vesicles that help in transferring substances into the cytoplasm of the cell.
