BOTANY

Detailed explanation-1: -Phagocytosis is a special form of endocytosis in which large particles such as microorganisms and dead cells are ingested via large endocytic vesicles called phagosomes.

Detailed explanation-2: -There are two types of vesicle transport, endocytosis and exocytosis (illustrated in Figure below). Both processes are active transport processes, requiring energy.

Detailed explanation-3: -Endocytosis (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.

Detailed explanation-4: -Vesicle formation is used as a gateway for the entry of extracellular substances into the cell or for recycling membrane components. Vesicle formation is thus related to various cellular functions that are accomplished through endocytosis.

Detailed explanation-5: -Exocytosis is a form of bulk transport during which large numbers of molecules are transported out of the cell. In exocytosis, a vesicle (a small, membrane-bound compartment) containing the molecules to be released fuses with the cell membrane, and the contents of the vesicle are expelled.
