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 else can I help you with?
What kind of water potential do hypertonic solutions have?
Hypertonic solutions have a lower water potential compared to the surrounding medium. This causes water to move out of the cell, leading to cell shrinkage or crenation.
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.
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.
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).
When comparing two solutions the solution with a greater concentration of solutions is called hypertonic why is a solution with the lower concentration of solutes is called?
The one that is lower is called hypotonic. But these are all comparisons between two things. There is another solution involved called isotonic. This one is equal to the one that you are comparing it with. Hypotonic means below and hypertonic means above some thing that you are comparing them with.
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 kind of water potential do hypertonic solutions have?
Hypertonic solutions have a lower water potential compared to the surrounding medium. This causes water to move out of the cell, leading to cell shrinkage or crenation.
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 do isotonic hypotonic and hypertonic deal with?

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.

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.
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).
What is the relationship between the electric potential inside a conductor and its surrounding environment?
The electric potential inside a conductor is constant and equal to the potential at its surface. This is because the electric field inside a conductor is zero, and any excess charge on the conductor redistributes itself to maintain equilibrium with the surrounding environment.

The one that is lower is called hypotonic. But these are all comparisons between two things. There is another solution involved called isotonic. This one is equal to the one that you are comparing it with. Hypotonic means below and hypertonic means above some thing that you are comparing them with.
Is sodium chloride 1.8 percent hyper tonic?
Yes, a sodium chloride solution at a concentration of 1.8% would be hypertonic, meaning it has a higher solute concentration compared to the surrounding cells or environment. This can cause water to move out of the cells through osmosis, leading to dehydration and potential cell shrinkage.
