effect of solutions on animal and plant cells?

Question

What is the effect of HYPOTONIC, HYPERTONIC, and ISOTONIC SOLUTION on animal and plant cells?

Answer 1

isotonic have no effect
hypertonic effect:
In plant cells, the effect is more dramatic. The cell membrane pulls away from the cell wall, but the cell remains joined to the adjacent cells at points called plasmodesmata. Thus, the cell takes on the appearance of a pincushion, with the plasmodesmata almost ceasing to function because they have become so constricted. This condition is known as plasmolysis.

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.

Because a cell that is hypertonic has a greater concentration of water than its environment, osmosis transports water out of the cell.

Saltwater is hypertonic to the fish that live in it. The fish 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 through their kidneys.

The opposite of hypertonic is hypotonic, where the net movement of water is into the cell; the intermediate state is called isotonic, where there is no net movement of water. This does not mean, however, that water is not moving; it means that water is moving both ways but with equal force, so the water concentration on either side of the cell membrane ultimately does not change. When a hypotonic cell dies, its remains are absorbed by other similar hypotonic cells.

Answer 2

I'm guessing you're asking as part of a question you've been set for some collegework?

It's to do with osmosis. Isotonic will have no effect, hypertonic will make the cells swell up with water. Hypotonic will make them shrivel up

Answer 3

In a hypotonic solution the animal cell will burst, the solution molecule came into the cell, and the cell becomes larger and larger, as it continued to go inside the cell it produce the cell to swallow up to the point to lyse or rupture occur. In the plant cell will swell up but not burst due to the rigid cell wall (creates a turgid pressure) In a hypertonic solution water will leave the cells causing the animal cells to shrivel up and the plant cell to plasmolysis (the cell comes away from the rigid cell wall) Isotonic solution no change in animal or plant cells

Answer 4

Hypotonic- Gains water, cell swells (possibly bursts--> cell dies)

Hypertonic- loses water, cell shrinks (possibly dies)

Isotonic- Equilibrium, no net change.

Answer 5

Hypotonic solution -> water moves in cell
Animal cell: swell and may burst
Plant cell: becomes turgid. will not burst because of its tough rigid cell wall preventing further expansion

Hypertonic solution -> water moves out cell
Animal cell and plant cell: plasmolysis

Isotonic solution -> no net water movement
Animal and plant cell: no difference observed
