Detailed explanation-1: -Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with th e cell membr ane. The membrane folds over the substance and it becomes completely enclosed by the membrane. At this point a membrane-bound sac, or vesicle, pinches off and moves the substance into the cytosol.

Detailed explanation-2: -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.

Detailed explanation-3: -Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another. When a cell makes proteins, transporter vesicles help move these proteins to the Golgi apparatus for further sorting and refining.

Detailed explanation-4: -Endocytosis is the process of a cell engulfing and bringing a material or particle from outside the cell inside the cell by enveloping it with the cell membrane. In exocytosis, the plasma membrane becomes fused with vesicles, releasing the contents to the cell’s exterior.

Detailed explanation-5: -In a biological cell, water molecules can pass both ways and a net movement always means that more molecules of water travel from higher to lower concentrations than the other way round. Remember, that the diffusion of water molecules is called osmosis.
