Question

what is meant by endocytosis and exocytosis?

Answer 1

The process of endocytosis and exocytosis are explained below:

Explanation:

• As the name suggests, in the process of endocytosis, materials are taken within a cell. The desired material is internalized by the plasma membrane of the particular cell.

• On the other hand, in exocytosis  materials are transported outside of a cell. The process of exocytosis happens against the concentration gradient and hence it is a form of active transport.

Answer 2

Answer:

Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell.

While, Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.
