define the following endocytosis, phagocytosis, exocytosis
Answers
Answer:
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material
Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. ... The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell.
the release of cellular substances (such as secretory products) contained in cell vesicles by fusion of the vesicular membrane with the plasma membrane and subsequent release of the contents to the exterior of the cell.
Answer:
endocytosis
the taking in of matter by a living cell by invagination of its membrane to form a vacuole.
phagocytosis
the ingestion of bacteria or other material by phagocytes and amoeboid protozoans.
exocytosis
a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
