Phagocytosis:

Phagocytosis , often called 'cell eating', is a fundamental biological process where a cell actively engulfs large particles, such as bacteria, viruses, or dead cellular debris. The cell extends its membrane to surround the particle, forming an internal vesicle called a phagosome. This is a crucial mechanism for both nutrition in single-celled organisms and for immune defence in multicellular organisms. What is the process of phagocytosis in biology described with stages & functions. Does it require energy. Learn how it works with meaning, examples, & labeled diagram Phagocytosis is a physiological cellular process wherein a cell engulfs a particle having a diameter >0.5 µm.
