Final answer:
Endocytosis is a form of active transport that moves particles into a cell by invaginating the plasma membrane and forming a pocket around the target particle. There are different types of endocytosis, including phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Step-by-step explanation:
Endocytosis is a form of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. There are different variations of endocytosis, but all share a common characteristic: The plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane. The three types of endocytosis are phagocytosis, pinocytosis, and receptor-mediated endocytosis.
