Detailed explanation-1: -This process of engulfing or taking in a matter by the projections or invaginations of the cell membrane to form a vacuole is called endocytosis.

Detailed explanation-2: -Endocytosis is the process in which cells absorb molecules by engulfing them. The cell membrane engulfs food and other materials by endocytosis. The plasma membrane creates a small deformation inward, called as an invagination, in which the substance to be transported is captured.

Detailed explanation-3: -Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle. These can include things like nutrients to support the cell or pathogens that immune cells engulf and destroy.

Detailed explanation-4: -Endocytosis is a type 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.

Detailed explanation-5: -Like the active transport processes that move ions and small molecules via carrier proteins, bulk transport is an energy-requiring (and, in fact, energy-intensive) process. Here, we’ll look at the different modes of bulk transport: phagocytosis, pinocytosis, receptor-mediated endocytosis, and exocytosis.
