Detailed explanation-1: -Vesicles or other bodies in the cytoplasm move macromolecules or large particles across the plasma membrane. There are two types of vesicle transport, endocytosis and exocytosis (illustrated in Figure below). Both processes are active transport processes, requiring energy.

Detailed explanation-2: -Endocytosis and exocytosis are the names given to the active, bulk transport of products across the cell membrane. These processes allow larger molecules that cannot diffuse through the lipid bilayer to cross the membrane. Endocytosis is the process by which substances are engulfed into the cell.

Detailed explanation-3: -The correct answer is that a-Endocytosis and exocytosis involve active transport. Both endocytosis and exocytosis require the use of ATP for the cell to enclose the particles being brought in, or to move the vesicle out of the cell, this makes both of these processes active transport.

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.
