expalin the three types of osmosis processes
Answers
Answer:
The three types of osmotic conditions include- hypertonic, isotonic, and hypotonic.
Answer:
Osmotic Solutions
There are three different types of solutions:
Isotonic Solution
Hypertonic Solution
Hypotonic Solution
An isotonic solution is one that has the same concentration of solutes both inside and outside the cell.
A hypertonic solution is one that has a higher solute concentration outside the cell than inside.
A hypotonic solution is the one that has a higher solute concentration inside the cell than outside.
Types of Osmosis
Osmosis is of two types:
Endosmosis– When a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid or de-plasmolyzes. This is known as endosmosis.
Exosmosis– When a substance is placed in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or plasmolyzes. This is known as exosmosis.

Effect of Osmosis on Cells
Osmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.
An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.
The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure.
