Understand that endocytosis is a cellular process where cells engulf external substances, bringing them into the cell.
Recognize the three types of endocytosis: phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Phagocytosis involves the engulfing of large particles or cells, often referred to as 'cell eating.'
Pinocytosis is the process of engulfing liquid substances, often called 'cell drinking.'
Receptor-mediated endocytosis involves the specific uptake of molecules based on receptor-ligand interactions on the cell membrane.
