NettetEndocytosis ( endo = internal, cytosis = transport mechanism) is a general term for the various types of active transport that move particles into a cell by enclosing them in a vesicle made out of plasma membrane. There are variations of endocytosis, but all follow the same basic process. NettetWater moves in and out of the cell: Osmosis is the process by which solvent particles flow from a dilute solution to one that is more concentrated. Diffusion, in contrast, is the movement of particles from a location of higher concentration to one of lower concentration. Water moves by osmosis, which is a type of diffusion, into and out of …

NettetAs a result, oxygen will diffuse from outside the cell directly through the lipid bilayer of the membrane and into the cytoplasm within the cell. On the other hand, because cells produce CO 2 as a byproduct of metabolism, CO 2 concentrations rise within the cytoplasm; therefore, CO 2 will move from the cell through the lipid bilayer and into the … Nettet39 Questions Show answers Question 1 30 seconds Q.
