Verified step by step guidance

Understand the concept of endocytosis: Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of the plasma membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
Differentiate between types of endocytosis: There are two main types of endocytosis - phagocytosis and pinocytosis. Phagocytosis involves the engulfing of large particles or even whole cells, while pinocytosis involves the uptake of fluids and dissolved substances.
Identify the process for large particles: Phagocytosis is the specific type of endocytosis where the cell engulfs large particles or microorganisms. This is often referred to as 'cell eating'.
Consider the role of vesicles: In phagocytosis, the cell membrane extends around the particle, forming a vesicle known as a phagosome, which then fuses with a lysosome for digestion.
Clarify the incorrect options: Pinocytosis is for fluid uptake, and exocytosis is the process of vesicles fusing with the plasma membrane to release contents outside the cell, which is the opposite of endocytosis.
