Endocytosis is a process in which a cell surrounds a substance outside of the cell by extending its cell membrane and cytoplasm and then takes it into the cell. Amoeba do this in order to feed on bacteria and other tiny organisms. Certain white blood cells also do this in order to rid the body of pathogens.
Endocytosis is a cellular process in which cells take in substances from the external environment by engulfing them within a vesicle formed from the cell membrane. This process helps regulate the intake of nutrients, signaling molecules, and other substances into the cell. There are different types of endocytosis, including phagocytosis, pinocytosis, and receptor-mediated endocytosis.
It is similar to diffusion. It is when a cell's membrane engulfs a particle and the remaining part of the membrane turns into a vacuole around the particle. This occurs when the particle is too large to diffuse into the cell on its own.
Some mechanisms that allow movement of materials across a plasma membrane include simple diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Each of these mechanisms plays a specific role in the transport of substances such as nutrients, ions, and waste products across the cell membrane.
