Detailed explanation-1: -Phagocytosis is an important process for nutrition in unicellular organisms, while in multicellular organisms it is found in specialized cells called phagocytes. Phagocytosis consists in recognition and ingestion of particles larger than 0.5 m into a plasma membrane derived vesicle, known as phagosome.
Detailed explanation-2: -Receptors on the cell surface bind ligand molecules on the target, such as a pathogen, dead cell, or bead. As receptors bind more and more ligand molecules, the cell membrane progressively engulfs the target. Upon full engulfment, a phagosome is formed, which fuses with lysosomes, leading to digestion of the target.
Detailed explanation-3: -Phagocytosis is the process of sensing and taking in particles larger than 0.5 m. The particle is internalized into a distinctive organelle, the phagosome. This phagosome subsequently changes the structure of its membrane and the composition of its contents in a process known as phagosome maturation (3).
Detailed explanation-4: -Overview. The chemicals also attract white blood cells that “eat” microorganisms and dead or damaged cells. The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes.
Detailed explanation-5: -Listen to pronunciation. (FA-goh-sy-TOH-sis) The process by which a phagocyte (a type of white blood cell) surrounds and destroys foreign substances (such as bacteria) and removes dead cells.
