How would a (i)plant cell (i)animal cell behave when placed in hypotonic solution on nacl
Answers
In animal cells, being in a hypertonic environment results in crenation, where the shape of the cell becomes distorted and wrinkled as water leaves the cell. Some organisms have evolved methods of venting Hypertonicity; for example, saltwater is hypertonic to the fish that live in it. Since they cannot isolate themselves from osmotic water loss, because they need a large surface area in their gills for gas exchange, they respond by drinking large amounts of water, and excreting the salt. This process is called osmoregulation. An example of an animal cell showing the affects of hypertonicity is when your fingers wrinkle.

HOW IT AFFECTS PLANT CELLS;
When a plant cell is placed in a hypertonic solution, the water inside the cells are drawn out by osmosis. The vacuoles decrease in size. The cytoplasm also shrinks away from the cellulose cell wall and plasmolysisoccurs. This causes a lack of structure for the plant and causes it to wilt, or become flaccid.

Hypotonic
The word "HYPO" means less, in this case there are less solute molecules outside the cell. Cells hypotonic to their surrounding solutions cause water to move into the cell and cause it to expand. The cell has a smaller number of solutes than the solution outside of the cell membrane. A hypotonic solution is a solution having a lesser solute concentration than the cytosol. It contains a lesser concentration of impermeable solutes on the external side of the membrane. When a cell’s cytoplasm is bathed in a hypotonic solution the water will be drawn out of the solution and into the cell by osmosis. If water molecules continue to diffuse into the cell, it will cause the cell to swell, up to the point that cytolysis (rupture) may occur. The opposite of a hypertonic environment is a hypotonic one, where the net movement of water is into the cell. If the cell contains more impermeable solute than its surroundings, water will enter it.
HOW IT AFFECTS ANIMAL CELLS;
In an animal cell, hypotonic solutions cause them to swell, they become bloated and triple their original size. By the time they have reached triple their size (how long this takes depends on each individual cell) they burst like a balloon and die
HOW IT AFFECTS PLANT CELLS;
When plants are placed in water, the water enters their cells (this is because their sap has a strong solution). The water enters the plant through osmosis and fills up the cell with water to its maximum capacity. A strong cell wall stops the cells from bursting (as in animal cells) and makes the plant to become turgid (becomes rigid/stiff because of water.)
In hypotonic solution , water molecules are free to pass across the plasma membrane of the cell in both direction but more wattle enters the cell as compared to the water molecules which leaves. In this case the net result is that the cell swells up that is becomes inflated . In the case of animal cells like RBC it may be Swollen up and can ultimately burst that is haemolysed. But in the case of plant cell it is a little different because of the presence of cell wall . When the water molecules entering in the Cell results in the swelling of the cell, the cell membrane of the cell exerts pressure on the cell wall because cell wall is a dead and firm wall it also exerts equal and opposite pressure on the internal membrane of the cell as a result of which plant cell do not bursts and it is capable of handling much pressure as compared to animal cell.
