Answers

B - exocytosis.

Think of like materials EXitig the cell via EXocytosis

Final answer:

Exocytosis is the process that refers to materials leaving the cell. It involves the enveloping of waste material in a membrane which fuses with the plasma membrane's interior, allowing for expulsion of waste into the extracellular space.

Explanation:

The term that refers to materials leaving the cell is B. Exocytosis. Exocytosis is essentially the process of moving materials from within the cell to the extracellular fluid. This is achieved through the enveloping of waste material in a membrane which then fuses with the plasma membrane's interior. This fusion causes the membranous envelope to open, allowing the expulsion of waste materials into the extracellular space. Examples of this process include cells like those of the stomach or pancreas, which manufacture and secrete enzymes via exocytosis, or endocrine cells releasing hormones throughout the body.
