What is the Difference Between Endocytosis and Phagocytosis?
🆚 Go to Comparative Table 🆚Endocytosis and phagocytosis are both processes by which cells engulf and internalize materials, but they differ in the size of the particles they target and their specific functions. Here are the key differences between the two:
- Endocytosis: This is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. The plasma membrane of the cell invaginates, forming a pocket around the target particle, which then pinches off to form an endosome. Endocytosis is composed of three categories: phagocytosis, pinocytosis, and receptor-mediated endocytosis.
- Phagocytosis: This is a specific type of endocytosis that involves the engulfment of large particles, such as bacteria, cell debris, or even intact cells. In phagocytosis, the cell membrane forms a vesicle around the large solid matter, known as a phagosome. This process is primarily carried out by two types of white blood cells, macrophages and neutrophils, which are responsible for eliminating pathogens and removing aged or dead cells from tissues.
In summary, the main differences between endocytosis and phagocytosis are:
- Endocytosis is a broader process that includes phagocytosis and pinocytosis, while phagocytosis is a specific type of endocytosis that targets large particles.
- Phagocytosis is primarily a defense mechanism, where cells engulf and destroy pathogens and other large particles, while endocytosis serves various metabolic purposes.

Comparative Table: Endocytosis vs Phagocytosis
Here is a table comparing the differences between endocytosis and phagocytosis:
Feature | Endocytosis | Phagocytosis |
---|---|---|
Definition | The process by which a cell takes in molecules from the extracellular fluid. | A form of endocytosis in which a cell consumes an entire other cell or macromolecule. |
Process | The cell membrane forms a vesicle around the matter before taking it in. | The cell engulfs large solid matter by forming phagosomes. |
Purpose | Used for various metabolic purposes, such as taking in macromolecules, particles, fluids, dead cells, enzymes, hormones, and cell debris. | Used as a defense mechanism, engulfing large solid particles including dead cells, cell debris, bacteria, pathogens, small mineral particles, and dust particles. |
Types | Endocytosis is composed of three categories: phagocytosis, pinocytosis, and receptor-mediated endocytosis. | Phagocytosis is one of the three categories of endocytosis. |
Endocytosis is a broader process that involves the cell taking in various substances, while phagocytosis is a specific type of endocytosis where the cell engulfs large particles or cells.
