Question

Assertion (A): Endocytosis takes place only in animal cells.

Reason (R): Animal cell does not possess cell wall.

Answer 1

Correct option: (a) Both assertion(A) and reason (R) are true, and reason (R) is the correct explanation for assertion.

• The process by which materials move into the cell by engulfing of the food and other substances from the external environment is known as endocytosis.
• This is not observed in plant cells because a tough and rigid cell wall is present in them.
• Animal cells lack a cell wall outside the plasma membrane. Hence endocytosis takes place.
• Therefore, Both assertion(A) and reason (R) are true and reason(R) is the correct explanation for assertion(A).
