Moving “Big stuff” out
A
Endocytosis
B
Exocytosis
C
Diffusion
D
Osmosis
Explanation: 

Detailed explanation-1: -Exocytosis is when a cell uses secretory vesicles to expel materials or transport large molecules to the exterior of the cell. The vesicle then fuses with the plasma membrane and pushes the particles out of the cell into the extracellular fluid.

Detailed explanation-2: -Exocytosis (exo = external, cytosis = transport mechanism) is a form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.

Detailed explanation-3: -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-4: -Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin. Newly made membrane proteins and membrane lipids are moved on top the plasma membrane by exocytosis.
