Phagocytosis and Pinocytosis – Difference and Comparision
Pinocytosis is a process where cells engulf and ingest extracellular fluid and dissolved substances. The difference between phagocytosis and pinocytosis are given below:
Feature | Phagocytosis | Pinocytosis |
---|---|---|
Definition | Engulfing large particles or cells | Engulfing extracellular fluid and dissolved substances |
Type of Material | Solid particles, bacteria, and dead cells | Liquids and small molecules |
Vesicle Size | Large vesicles called phagosomes | Small vesicles |
Specificity | Often selective, recognizing specific particles | Non-selective, takes in all nearby fluid |
Energy Requirement | Requires energy (active process) | Requires energy (active process) |
Role in the Body | Part of the immune response, clearing debris | Nutrient absorption and cellular fluid regulation |
Example Cells | Macrophages, neutrophils | Most cells, especially in nutrient absorption areas |
Steps of Phagocytosis
Phagocytosis is a process by which certain cells engulf and digest large particles or microorganisms. Understanding the steps of phagocytosis in order helps explain how cells engulf and destroy harmful particles. In this article, we will learn about phagocytosis and its function.
