Describe two solutions that have the same concentration of solutes relative to one another?
isotonic or isoosmotic
In a hypo tonic solution will a cell gain or lose water or no net change?
The cell will not loose or gain water.An isotonic solution means that the amount of solutes outside the cell is similar or equal to the amount of solutes inside the cell. Water is moving by osmosis both in and out of the cell at equal rates; the net movement of water is zero.A cell will lose water in a hypertonic solution (more solute in the surrounding environment) and gain water in a hypotonic solution (more solute in the cellular environment). Whether or not a solution is hypertonic, hypotonic, or isotonic is relative to the environment in the cell.
Why do herbaceous plants wilt when they do not have enough water and stand erect when they have water?
This relates to the type of solution the plant cells are exposed to. In general, there are 3 distinct types of solutions in nature: hypotonic, isotonic, and hypertonic. A hypotonic solution is one that has a low concentration of a solute relative to the solute concentration inside the cell, such as distilled water. An isotonic solution has the same solute concentration as the inside of the cell. A hypertonic solution has a higher concentration of solute than the inside of the cell.Back to the plants...When plants wilt, that means the are exposed to an isotonic solution. When this happens, the net amount of water moving between cells and the environment is equal. As a result, the cell becomes flaccid and the plant wilts.When plants stand erect, this is a result of turgor pressure. When in a hypotonic solution, such as distilled water, the plant cells absorb the water and store it in its central vacuole. The cell cytoplasm enlarges and pushes up against the sturdy cell walls. This cell is said to be turgid, or stable.
Is salt water dilute or concentrated?
The word 'dilute' is an inexact term. Hypotonic (less solute) and hypertonic (more solute) and isotonic (the same amount) are relative terms. What they mean is that a solution will either have less, more, or the same concentration of a given solute than the reference substance. It is important in cells because a hypertonic solution (such as salt water) will try to pull free water out of the cell, where the concentration of salt is less. A hypotonic solution will cause water to soak into the cells. Either situation may be undesirable. For osmosis, water will flow across a semipermeable membrane in the direction of the pressure gradient. It will always flow from the hypotonic solution into the hypertonic solution. Plants absorb water by creating a hypertonic state inside the root.
What are the Tonicity of the cell?
Cells can be placed in solutions with higher, lower, or equal concentration to the cell... 1. ISOTONIC: - a solution with equal concentration to the cell. - 0.9% NaCl solutions is isotonic to RBC (red blood cells). - isotonic solutions cause no net gain or loss of water to a cell. 2. HYPOTONIC: - solute concentration is greater on the inside of the cell (or: the outer solution has less concentration than inside). - >0.9% NaCl solutions is hypotonic to RBC (red blood cells). - causes swelling, could burst (lyse) - net gain of water 3. HYPERTONIC: - <0.9% NaCl solutions is hypertonic to RBC (red blood cells). - net loss of water from the cell. - solute concentration is greater on the outside of the cell (or: the outer solution is greater concentration than the inside). - causes the cell shrink (crenation in RBC)
Is 0.8 NaCl a hypertonic solution?
That depends entirely on what solution it is in. Hypotonic and hypertonic are relative terms to compare to solutions usually serperated by a seme-permeable membrane.
Explain why it is not enough just to say that a solution is hypertonic?
hypertonic and hypotonic are relative terms. A solution that is hypertonic to tap H2O could be hypotonic to seawater. In using these terms, you must provide a comparison, as in 'the solution is hypertonic to the cells cytoplasm'.
Describe two solutions that have the same concentration of solutes relative to one another?
isotonic or isoosmotic
Cell is placed in a solution If the cell is observed to shrink the solution must be relative to the interior of the cell?
hypertonic
What hypertonic means to illustrate equilibrium?
Hypertonic is when you have a high concentration of solute relative to the solvent. For example, salt water is a hypertonic solution with vast amounts of sodium, chlorine, potassium, and iodine dissolved in water.
How does ten percent salt water effect a cell containing ninety seven percent water?
Anytime there is a semipermeable membrane and water with dissolved ions on both sides of the membrane you have a situation where osmosis can occur. If the solutions on each side of the membrane are equal in concentration it is said they are "isotonic" and no net movement of water will occur. If the two solutions are not equal in concentration, then one is hypertonic (more dissolved solutes) and the other is hypotonic (fewer dissolved solutes). In the case of the 10% salt solution, that is hypertonic relative to the cell. Water will move towards the hypertonic side, so water will move out of the cell and into the salt water--in other words, the cell will shrivel up (and possibly die). If instead you put the cell in distilled water, then water would rush into the cell (since it is hypertonic relative to distilled water). In that case the cell would swell up and burst. Isotonic saline solution is 0.85% or 0.9%--not quite 1% salt. They give isotonic saline intravenously when a person is dehydrated. Hope that helps. ~Kevin

A solution that contains a lower solute concentration than the cytoplasm of a cell is called?
This cell would be described as hypotonic. That means the higher osmotic pressure is in the cell and it is swollen because water is going down its concentration gradient into the cell and is less concentrated out side the cell.

Isotonic.. No water is gonna move in or out

What terms describes a solution with a higher concentration of dissolved substances relative to another solution?
You are probably looking for "dilute" but that is wrong, dilute is relative. A dilute solution of table salt (sodium chloride) can be a very different concentration to a dilute solution of slaked lime (calcium hydroxide).
