12 if a cel needs a large molecule, such as a polysaccharide, it must fuse with the cell membrane to bring it inside the cell in a process known as "Endo" in the word endocytosis means 13. In active transport, molecules that fuse with the cell membrane are encased in structures called so they can be taken inside the cell. 14. The three main type of endocytosis are and 15.

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.
