What is endocytosis in Class 9
Answers
Answer:
Endocytosis: It is the process of ingestion of materials by the cells through the plasma membrane. It describes all three similar processes: phagocytosis (cell eating), potocytosis (cell drinking) and receptor-mediated endocytosis.
Answer:
Endocytosis is the process by which cells take in substances from the outside by enveloping them in a vesicle. These could be substances that provide nourishment for the cell or infections that immune cells engulf and eliminate.
Explanation:
A cell can absorb any substance (liquid or solid) from the external environment through the process of endocytosis. De Duvecpined the term "endocytosis" in 1963.
Purpose of endocytosis:
It is either a process of eating pathogens to neutralise them or the process by which a cell obtains the nutrients and vital materials needed for its growth and replication from the external environment.
Endocytosis occurs when the cell membrane folds around the substance to be absorbed, creating a vesicular structure that finally pinches off from the membrane inside the cell.
