What is Exosmosis where does it takes place?
EXOSMOSIS. endosmosis occurs when a cell in placed in a strong hypotonic solution . the surrounding has a less dilute solution than the solution inside the cell. therefore water moves from its region of high pressure (inside the cell ) to its regin of low pressure ( surrounding water )thus shrinking the cell.
What is hypotonic solution?
A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.
What happens during Exosmosis?
Exosmosis. When a cell is placed in a hypertonic solution, the water moves out of the cell and the cell becomes flaccid. This movement of water out of the cell is known as exosmosis. This happens because the solute concentration of the surrounding solution is higher than that inside the cytoplasm.
What is the process of Endosmosis?
Osmosis –> It is the process of transfer of materials in and out of the cell in context to the environmental pressure. Endosmosis :- When the concentration is low inside a cell compared to the environment, water travels from outside to inside. Exosmosis :- It is the vice versa of Endosmosis.
What is hypertonic and hypotonic solution?
A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it, and a hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.
What is Deplasmolysis in biology?
deplasmolysis. A Dictionary of Plant Sciences. deplasmolysis The entrance of water into a plasmolysed (see PLASMOLYSIS) plant cell, causing the cell membrane to return to the cell wall. "deplasmolysis."
What is water potential in biology?
Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as capillary action (which is caused by surface tension). … These solutions have negative water potential, relative to the pure water reference.
Where does water go in a hypertonic solution?
Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.
