Do animal cells use endocytosis?

Answer 1

Yes

Endocytosis is essentially an engulfing process that is used to take different substances inside the cell. Certain immune cells also exhibit endocytosis, which aids in the destruction of foreign particles that enter the body.

Yes, animal cells use endocytosis to take in substances from their external environment. Endocytosis is a cellular process where the cell membrane invaginates or folds inward to form a vesicle that encloses the material to be transported into the cell. There are different types of endocytosis, including phagocytosis (engulfing solid particles), pinocytosis (engulfing liquid droplets), and receptor-mediated endocytosis (specific uptake of molecules bound to receptors).
