Final answer:
The statement is true; endocytosis is a cellular process wherein the cell membrane engulfs extracellular material and forms a vesicle to transport this material into the cytoplasm.
Step-by-step explanation:
The statement is true: In endocytosis, a cell engulfs material and brings it into the cell in a vesicle pinched off the cell membrane. Endocytosis is a form of active transport in which the cell membrane envelopes extracellular materials. This process can take various forms, such as phagocytosis (ingestion of large particles), pinocytosis (ingestion of fluid with small particles), and receptor-mediated endocytosis (targeted ingestion based on receptor-ligand binding).
Once the material is engulfed, the surrounding membrane pinches off to form a vesicle, which then becomes an intracellular vesicle, carrying substances inside the cell. These substances can be nutrients that are needed by the cell, pathogens that need to be destroyed, or other molecules that the cell requires. The vesicle membrane fuses with lysosomes or similar organelles within the cell for the breakdown and use of the material.
