Understand the concept of endocytosis: Endocytosis is a cellular process in which substances are brought into the cell. It involves the engulfing of external materials by the cell membrane, forming a vesicle that is then internalized.
Identify the types of endocytosis: There are two main types of endocytosis, which are phagocytosis and pinocytosis.
Define phagocytosis: Phagocytosis is the process by which cells ingest large particles, such as bacteria or dead cells. It is often referred to as 'cell eating.'
Define pinocytosis: Pinocytosis is the process by which cells ingest fluids and dissolved substances. It is often referred to as 'cell drinking.'
Differentiate endocytosis from exocytosis: Exocytosis is the process by which substances are expelled from the cell, the opposite of endocytosis.
