Explain endocytosis.

Explanation

During endocytosis, the cell membrane infolds around the material to form a vacuole and brings it into cytoplasm. These are two types of endocytosis:
1. Phagocytosis- Solid particles are engulfed by membrane, which folds around it and forms a vesicle. The enzymes digest the material and products are absorbed by cytoplasm.
2. Pinocytosis- Fluid droplests are engulfed by membrane, by forming vesicles around them .
