Question

plant cells dont undergo endocytosis. why?

Answer 1

In the process of endocytosis the plasma membrane of the cell changes shape and sends projections called pseudopodia. These projections then surround the particle to be engulfed and the plasma membranes of projections fuse together. As a result the particle comes inside the cell forming an intracellular vesicle. After endocytosis the shape of the cell regain its original form due to flexibility and elasticity of plasma membrane. In plant cells endocytosis is difficult due to the presence of cell wall. Rigid cell wall cannot be able to change the shapes as required to engulf the particles and it is not that flexible to regain its original shape.
