Exocytosis Endocytosis Exocytosis is used to ojoct substances trom the cell. Here, a cell ejects waste matertal into the outskde environment. Endocytosis is the revorse of exocyfosis, bringing matorial trom the outside of the coll to the inside, enclosod in vesickes. Endocytosis may be nonselectivo, as shown here, drawing in any and al molocukos noar the opening of the vosicle. Here, a white blood cll engults a yeast coll through phagocytosis, a form of nonspecitic endocytosis. Receptor-mediated endocytosis Cells lining blood vessels have created flud-iled vesicles through pinocytosis, nonspecific endocytosis of ukd. Receptor-mediatod endocylosis is a selective process in which only certain molecules bind to receptor proteins. Here, low-density lipoprotein (LDL) particles bind lo LDL receptors and are transported to the cell interior.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
