Which term means Cellular ingestion?

• A. Diameter
• B. Distal
• C. Elevate
• D. Endocytosis

Answer: (D)

Cellular uptake by engulfing material is called endocytosis. Endocytosis is the process where the cell membrane folds inward to surround external substances, forming a vesicle that brings the material into the cell. This is a specific mechanism for ingesting things like nutrients or particles, and it includes subtypes such as phagocytosis for solids and pinocytosis for fluids. It’s an active transport process that requires energy, and it contrasts with exocytosis, where substances exit the cell. The other terms don’t describe ingestion: diameter is a measurement across an object, distal means farther from a reference point, and elevate means to raise.
