GENERAL HISTOLOGY

Detailed explanation-1: -Cells ingest fluid, molecules, and particles by endocytosis, in which localized regions of the plasma membrane invaginate and pinch off to form endocytic vesicles. Many of the endocytosed molecules and particles end up in lysosomes, where they are degraded.

Detailed explanation-2: -These processes allow larger molecules that cannot diffuse through the lipid bilayer to cross the membrane. Endocytosis is the process by which substances are engulfed into the cell.

Detailed explanation-3: -Endocytosis and exocytosis are the mechanisms by which cells transport items that are too big to pass through the lipid bilayer of the cell membrane directly into or out of the cell. Exocytosis and endocytosis are two processes that allow large molecules, bacteria, and waste materials to pass through the cell membrane.
