Question

cell drinking; cell eating. both are modeled here and are examples of
a osmosis.
b diffusion.
c endocytosis.
d facilitated transport.

Explanation:

Cell - drinking (pinocytosis) and cell - eating (phagocytosis) are types of endocytosis. Endocytosis is the process by which cells take in substances by engulfing them with their cell membrane. Osmosis is the movement of water across a semi - permeable membrane. Diffusion is the movement of substances from an area of high concentration to an area of low concentration. Facilitated transport involves the use of transport proteins to move substances across the membrane.

Answer:

C. endocytosis
