Q. During endocytosis, the cell
A) Divides its cytoplasm during mitosis
B) Digests itself
C) Engulfs and internalises materials using its membrane
D) Enables the extracellular digestion of large molecules
Explanation
Endocytosis is the process by which materials enter a cell without passing through the plasma membrane. The membrane folds around material outside the cell, resulting in the formation of sac-like vesicle into which the material is incorporated. This vesicle is then pinched off from the cell surface so that is lies within the cell.
