Endosytosis

Exocytosis
a type of membrane transport that does not require energy to move substances across cell membranes
Passive transport
a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy.”
Active transport
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
