Phagocytosis is exemplified by ______. phagocytosis is exemplified by _______. a cell manufacturing a substance that is first en
closed in a vesicle and then later secreted from the cell most types of white blood cells ingesting bacteria, viruses, and other foreign substances oxygen entering cells by diffusion a cell sampling a tiny amount of extracellular material none of the listed examples describes phagocytosis
Phagocytes refer to the procedure by which some kind of living cells known as phagocytes engulfs or ingest other cells or particles. The phagocyte may be a free-living one-celled species, like an amoeba, or one of the body cells, like a white blood cell.
In higher species, phagocytosis is mainly a defensive mechanism against infection and invasion of the body by the antigens, that is, foreign particles.
Thus, phagocytosis is illustrated by most types of white blood cells ingesting bacteria, viruses, and other foreign substances.
most types of white blood cells ingesting bacteria, viruses, and other foreign substances
Explanation:
Phagocytosis refers to the process wherein some specific cell types engulf the particles, pathogens, food or other cell types. It is a type of endocytosis and is exhibited by certain protists and white blood cells.
For example, white blood cells such as macrophages engulf the pathogens to kill them. During the process, cell membrane of the phagocytic white blood cells encloses pathogens such as bacterium followed by formation of a vacuole around it.
The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.
