Question

Write a note on endocytosis.

Answer 1

Endocytosis:
The ingestion of materials by the cells through the plasma membrane is called endocytosis. It includes three processes—that is,
(a) phagocytosis (cell eating),
(b) photocytosis (cell drinking), and
(c) receptor-mediated endocytosis.
All of these processes require energy, so these may be considered as different forms of active transport.
