Write a note on endocytosis.

Endocytosis is the process of capturing a substances or particle from outside the cell by engulfing it with the plasma membrane, and bringing it into the cell. There are three types of endocytosis: 1. Phagocytosis, 2. Pinocytosis and 3. Receptor mediated endocytosis.

Endocytosis helps to bring molecules inside the cells. Endocytosis is an active transport process as it requires energy.
