OBSERVING OSMOSIS IN PLANT CELLS?
You can observe osmosis in plant cells by placing a plant cell in a hypertonic or hypotonic solution and observing any changes in cell size and shape due to the movement of water. Hypertonic solution will cause cell to shrink (plasmolysis) and hypotonic solution will cause cell to swell. You can use a microscope to observe these changes in plant cells during osmosis.
What is deplasmolysis?
When a plant cell is placed in a hypotonic solution then plant cell gains water by osmosis there is swelling of the contents of the cell away from the cell wall ,this phenomenon is known as deplasmolyzis
What happens to a plant cell if it is place in a hypotonic solution?
Osmosis works for any type of cell. Because of a lower concentration of solute inside the cell then out, the water would rush to where the solute is in an attempt to make it even. It would retain its shape because of its cell wall making it rigid which is absent in animal cells which is prone to swelling and making it burst.
What solution causes a cell to swell?
Any solution with more H2O than inside the cell will cause the cell to swell. Animal cells will burst under a lot of pressure, but plant cells will not, due to the presence of a cell well surrounding the cell. In other words, a hypotonic solution will cause a cell to swell, and a hypertonic solution will cause a cell to shrink. Hypo -> hyper
What chages in cell volume will occur if a cell is placed in a hypotonic sloution?
A change in cell volume that will occur when a cell is placed in a hypotonic solution is that a cell will expand. Water will move from the solution into the cell. If enough water enters the cell the cell will expand and eventually burst.

What happens to plant cells when placed in a hypotonic solution?
When a plant cell is placed in an hypotonic solution it becomes swollen and hard. The cell takes in water by osmosis and starts to swell, but the cell wall prevents it from bursting.

When a plant cell is placed in a hypotonic solution then plant cell gains water by osmosis there is swelling of the contents of the cell away from the cell wall ,this phenomenon is known as deplasmolyzis
What happens to both plant and animal cells when they are placed into a solution that is hypotonic?
Both types of cells will have endo-osmosis and will become turgid
When can tell that plant cells are undergoing osmosis without using a scale?
You can tell that plant cells are undergoing osmosis if they swell or shrink. When plant cells are placed in a hypertonic solution, they lose water and shrink. Conversely, when they are placed in a hypotonic solution, they gain water and swell. These changes in cell size indicate that osmosis is occurring.

When a plant cell is exposed to a hypotonic solution what happens to the turgitidy?
When a plant cell is exposed to a hypotonic solution, water enters the cell via osmosis, causing it to swell. This influx of water increases turgor pressure, which is the pressure of the cell contents against the cell wall. As a result, the cell becomes turgid, providing structural support to the plant. This turgidity is essential for maintaining the plant's rigidity and overall health.
When plant is place in hypotonic solution?
the plant cell shrinks and this is because concentration is high in the solution and less in plant cell
Do plants like to be hypertonic or hypotonic in their environment?
Plants prefer to be in a hypotonic environment, where the surrounding solution has a lower solute concentration than the plant cells. This allows for water to flow into the plant cells through osmosis, maintaining turgor pressure and supporting cell structure and function. In a hypertonic environment, water would flow out of the plant cells, causing them to shrink and wilt.
Why does a cell plant burst in a hypo tonic solution?
A plant cell bursts in a hypotonic solution because water enters the cell through osmosis, causing it to swell. The increased water uptake in a hypotonic environment creates pressure on the cell wall, eventually leading to bursting.
What solution causes a cell to swell?
Any solution with more H2O than inside the cell will cause the cell to swell. Animal cells will burst under a lot of pressure, but plant cells will not, due to the presence of a cell well surrounding the cell.

Does osmosis flow in or out of a plant?
In a general sense, osmosis flows into a plant. Provided that osmosis is the diffusion of water molecules that pass through a semipermeable membrane to equalize the overall concentration, there are a few conditions where the plant cells will respond to different forms of solutions; as evident by the cell's ability to gain or lose water.Hypotonic Solution:(hypo-, below)While an animal cell would lyse, or burst, this is the ideal solution for a plant cell. For the reason that the solute concentration in the solution is lower than the cell's solute concentration, where the net flow of water enters the cell.Isotonic Solution:(iso-, same)In an isotonic solution, the cell's volume remains constant. The net flow of water is facilitated, where the rate of water that enters and exits the cell is equal; meaning that the solute concentration of the cell, and the solution is also the same.Hypertonic Solution:(hyper-, above)In contrast to a hypotonic solution, the solution has a higher concentration of solutes, and water exits the cell; a cell may possibly die from dehydration, or plasmolysis, a process where the cell shrivels from the excessive loss of water.To conclude, osmosis is a process that directs the flow of water into regular plant cells, in the same way that a cell placed in a hypotonic solution would inflate, since the water molecules move toward the side of a selectively permeable membrane with a higher solute concentration. Even more, hypotonic, isotonic, and hypertonic solutions are terms used to describe tonicity, cells in relation to their environment that includes the application of osmosis.
