Question

explain the terms : a) endocytosis , b) plasmolysis

Tell me fast answer ​

Answer 1

Answer:

a)endocytosis 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. Endocytosis includes pinocytosis (cell drinking) and phagocytosis (cell eating). It is a form of active transport

b)plasmolysis Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell. Through observation of plasmolysis and deplasmolysis, it is possible to determine the tonicity of the cell's environment as well as the rate solute molecules cross the cellular membrane

Answer 2

Explanation:

plasmolysis happens when a cell is kept in hypertonic solution and the the plasma membrane moves away from the cell membrane it happens due to exosmosis process.
