water potential measures the tendency of water to move from one region to another. In the case of osmosis occurring through the membrane of a plant cell, the water potential is the sum of the solute potential and the pressure potential.
The question states the pressure potential is nil. Therefore, the water potential is a direct measure of the solute potential.
The question also states that the water potential within the cell is lower than that of its surroundings. This means the solute potential within the cell is also lower than that of its surroundings Hence, there is more solutes outside the cell and less solutes inside the cell.
This type of solute gradient will cause solvent to move out of the cell. Therefore the cell is hypotonic to its environment.

What do isotonic hypotonic and hypertonic deal with?
A hypertonic solution is one containing more solute, a hypotonic solution contains more water, and an isotonic solution contains equal amounts of solute and water. Whether a solution is hypertonic, hypotonic, or isotonic can determine what happens to the cell. In a hypertonic solution, solute will diffuse into the cell down the concentration gradient. In a hypotonic solution, water will move into the cell by osmosis down a water potential gradient, and in an isotonic solution nothing will happen because the concentration and water potential are the same both inside and outside the cell.
When a human red blood cell is placed in a hypertonic environment it will?
It will undergo crenation. This means that the red blood cell will shrink in size and become shrivelled-looking. This is due to osmosis, which is the net movement of water molecules from a region of higher water potential (red blood cell) to a region of lower water potential (hypertonic solution) through a partially-permeable membrane (cell membrane).
Why the tissue fluid surrounding human cells must be isotonic?
In a hypotonic solution, the water potential of the environment is higher. Since water travels from areas of high water potential to low water potential, it will flow into the cell faster than it can be removed. The cell, which lacks a pressure-resisting wall, will swell and soon burst. In a hypertonic solution, it's the opposite. The water potential of the environment is lower, so the water will flow from inside of the cell to outside. The cell will basically shrivel. Compare this to the final option. In an isotonic solution, the water potential in both the inside of the cell and the surrounding environment is zero. This means that there is no net movement of water, so the cell will neither burst nor shrivel and remain healthy.
Do animal cells prefer hypertonic or hypotonic solutions?
isotonic solution is when the cell content has the same solute potential as the solution the cell is in. therefore no net movement of molecules.when a animal cell is placed in a hypotonic solution (a solution containing less solute particles than inside cell e.g water) molecules move from a high water potential to a low one because diffusion. net movement is into the cell. because of this the cell swells and eventually burst. this is osmotic shock.in a hypertonic solution the net movement is out of the cell. the cell shrinks this is called crenation.plant cell have a cell wall so in a hypotonic solution the cell swells but doesn't not burst because of the strong structure of the cellulose cell wall.the cell becomes turgid.in a hypertonic solution the net movement is out of the cell because of the high solute conc outside the cell. the cell membrane begins to pull away from the cell wall. the cell is plasmolysed. when fully plasmolysed it is irreversible.
What kind of water potential do hypertonic solutions have?
higher
What happens to a cell that is placed in a hypertonic hypotonic and isotonic environment?
An Animal Cell in hypertonic solution will look shriveled due to osmotic effects on the cell. the hypertonic solution means there is more water potential outside of the cell, water moves from a low water potential to a high water potential. Therefore the water diffuses out of the cell decreasing the volume bringing the cell membrane in making it look shriveled up.
Do freshwater fish live in a hypotonic environment?
yes.freshwater has high water potential,making it hypotonic

What will the water do if you immerse a living cell into hypertonic solution?
When dealing with cells and their surrounding environment, if the outside of the cell is hypertonic (more salty), water will move out of the cell. This is an effort for the concentration of the salt to even out. The cell will shrink as a result.
What term describes the differences in the concentrations of a substance across a cells membrane?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
What is the difference between isotonic hypotonic and hypertonic solution?
The words isotonic, hypertonic, and hypotonic refer to the relationship between two solutions. - When two solutions are isotonic to one another, the two solutions have the same amount of solute as each other. - When a solution is hypertonic in reference to another solution, that solution has more solute than the other. - When a solution is hypotonic in reference to another solution, that solution has less solute than the other. - Thus, on a scale of INCREASING solutes, you could align three solutions like this: hypotonic --> isotonic --> hypertonic. Secondly, since substances move from a region of high concentration (more solute) to low concentration (less solute), remember that solutes will always move from a hypertonic solution to a hypotonic solution OR solvents will always move from a hypotonic solution to a hypertonic solution. A good way to remember this is to know that "hyper" means above (more than) and hypo means "below" (less than), e.g. in HYPERactive = being really energetic or more energetic than normal vs. HYPOthermia = being very cold or below the normal temperature. A way to figure out whether a solution is isotonic, hypertonic, or hypotonic in respect to another solution is to figure out the solutions tonacities. Tonacity is the measure of solute in a solution. Therefore, something hypertonic has more tonacity or more solute than another solution. Some people learn the term "solute potential," which has a similar concept to tonacity. Examples: A 0.4 mol glucose solution is isotonic to a 0.4 mol glucose solution. A 0.4 mol glucose solution is hypertonic to a 0.2 mol glucose solution. A 0.2 mol glucose solution is hypotonic to a 0.4 mol glucose solution.

What do cells tend to do that are placed in a hypertonic solution of pure water?
A hypertonic solution is one with more dissolved substances/less water/higher osmotic potential than another fluid. A cell placed in a solution with a lower water potential than itself will undergo exosmosis/water will move out the cell.
Will water move into or out of a plant cell if the cell has a higher water potential than the surrounding environment?
