What is indocytosis?

Answer 1

Endocytosis is an energetic process where cells absorb molecules by completely engulfing them. It is used by cells because the substances viable to them are larger molecules that can't pass through the membrane.

Answer 2

Endocytosis is a cellular process in which cells engulf external particles or fluids by enclosing them in a vesicle that is formed from the cell membrane. This process allows cells to take in nutrients, regulate signaling molecules, and perform other functions related to the uptake of materials from the extracellular environment.
