iii. Hypertonic solution​

Answer 1

$\huge\underline\frak{\fbox{AnSwEr :-}}$

i. Isotonic solutions:

Solutions having the same osmotic pressureare called isotonic solutions.Isotonic solutions have equimolarconcentrations. In isotonic solutions no flowof solutions, through semipermeablemembranes.

ii. Hypotonic solution:

When the osmotic pressure of solution is lessthan that of other solution.

It is calledhypotonic solution relative to other.

iii. Hypertonic solution:

When the osmotic pressure of a solution ishigher than that of other, it is called hypertonicsolution relative to another.

Isotonic Solution

A cell in an isotonic solution is in equilibrium with its surroundings, meaning the solute concentrations inside and outside are the same (iso means equal in Latin). In this state there is no concentration gradient and therefore, no large movement of water in or out. Water molecules do freely move in and out of the cell, however, and the rate of movement is the same in both directions.

Hypotonic Solution

A hypotonic solution has a lower solute concentration than inside the cell (the prefix hypo is Latin for under or below). The difference in concentration between the compartments causes water to enter the cell. Plant cells can tolerate this situation better than animal cells. In plants, the large central vacuole fills with water and water also flows into the intercellular space. The combination of these two effects causes turgor pressure which presses against the cell wall causing it to bulge out. The cell wall helps keep the cell from bursting. However, if left in a highly hypertonic solution, an animal cell will swell until it bursts and dies.

Hypertonic Solution

In Latin, the prefix hyper means over or above. Hypertonic solutions have a higher solute concentration than inside the cell. This causes water to rush out making the cell wrinkle or shrivel. This is clearly seen in red blood cells undergoing a process called crenation. Plant cells in a hypertonic solution can look like a pincushion because of what’s going on inside. The cell membrane pulls away from the cell wall but remains attached at points called plasmodesmata. Plasmodesmata are tiny channels between plant cells that are used for transport and communication. When the inner membrane shrinks, it constricts the plasmodesmata resulting in a condition called plasmolysis
