Question

Distinguish between endocytosis and pinocytosis. (4)

Answer 1

Endocytosis - 1. endocytosis is defined as the process engulfing a particle or substance from the external environment of the cell by capturing it within the cell membrane and bring it inside the cell.

2. endocytosis is basically composed of three categories: pinocytosis, receptor-mediated endocytosis, and phagocytosis.

3. in endocytosis particle and macromolecule both are taken inside the cell.

Phagocytosis - 1. phagocytosis is defined as the capturing of large matter (solid) inside the cell with the help of the formation of phagosomes.

2. phagocytosis comes under one of the three categories of endocytosis. therefore it is a part of endocytosis

3., unlike endocytosis, phagocytosis only allow particle inside the cell.
