Which of the Following Statements Concerning Endocytosis is TRUE

Question

Which of the following statements concerning endocytosis is TRUE?
A) This process occurs in both prokaryotes and eukaryotes.
B) Phagocytosis is a type of endocytosis in which liquids are brought into the cell.
C) Endocytosis produces a structure called a food vesicle.
D) Waste products and secretions are exported from the cell during endocytosis.
E) Endocytosis is a form of passive transport.

Accepted Answer

Endocytosis is the process by which cells take in material from the outside environment by engulfing it with the plasma membrane. This process produces a structure called a vesicle or endosome. In phagocytosis, solid materials are engulfed, while in pinocytosis, liquids are taken up. Endocytosis is a form of active transport, not passive transport, as it requires the expenditure of energy by the cell. Endocytosis occurs only in eukaryotic cells, not prokaryotic cells. The export of waste products and secretions is a function of exocytosis, not endocytosis.
