Question

Why is endocytosis found in animals only? class 9 brainly

Answer 1

Answer:

for endocytosis to occur, the outermost membrane should be flexible like the plasma membrane of animals. But in plant cell, cell wall is the outermost membrane which is very rigid. hence endocytosis occurs only in animals and not in plants.

Answer 2

Answer:

Animals are the only organisms that undergo endocytosis because they lack a cell wall. As a result, in animals as opposed to plants, the flow of chemicals within the cell is simpler.

Explanation:

• The act of a plasma membrane engulfing food and other substances from an external medium is known as endocytosis. Plant cells do not undergo endocytosis; only animal cells do.
• Animal cells and protists like protozoa exhibit endocytosis and exocytosis.
• Bulk transport across the plasma membrane in these organisms refers to the movement of huge numbers of small, large, and food particles.
• The development of transport or carrier vesicles occurs concurrently.
• The latter carry out bulk internal transit and are endocytotic.
• The process is known as endocytosis.
• Two forms of endocytosis exist. Pinocytosis and phagocytosis are them.
• Bulk transport is performed externally via exocytic vesicles. It's known as exocytosis. Secretion and excretion are carried out through exocytosis.
