Detailed explanation-1: -3 Pinocytosis. Pinocytosis is an endocytosis process whereby extracellular fluids or particles (0.5 µm or smaller) are ingested by the cell. Briefly, cell membranes endocytose the external substances and collect them inside the membrane-bound vesicles, which are then transferred inside the cell.

Detailed explanation-2: -Endocytosis A process in which a cell engulfs extracellular material through an inward folding of its plasma membrane.

Detailed explanation-3: -In endocytosis, the material to be internalized is surrounded by an area of plasma membrane, which then buds off inside the cell to form a vesicle containing the ingested material.

Detailed explanation-4: -Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

Detailed explanation-5: -Endocytosis involves cells taking in substances from outside the cell by engulfing them in a vesicle derived from the cell membrane. Exocytosis is where cells shift materials, such as waste products, from inside the cell to the extracellular space.
