Hard water is water with high mineral/salt content. I'm toldthat a potted plant watered with a salt solution dries out sooneror later. Is this true?

If so, would a plant survive if watered using hard-water?

How do i figure this out:

Part A

Consider a plant 20 cm tall growing in well watered soil. In a dark and humid greenhouse, in the middle of the night, you measure the turgor pressure of a living leaf cell of this plant using a probe inserted in the cell. You find that the turgor pressure is 1.9 MPa. Given the current conditions, what is your prediction of the osmotic potential of this cell?

Part B

If you were to study a similar cell (from question above), under similar environmental conditions (night, saturating humidity, turgor pressure = 1.9 MPa), found at the top of a redwood tree on a misty night in California. How would your prediction of the osmotic potential change if you knew that the cell was located at the top of a 100 m tall tree? Explain the reason for the change in your prediction using the water potential equation.

A hypertonic solution has a higher level of solutes so the water moves out of the cells to the surroundings

A hypertonic solution has a higher level of solutes so the water moves out of the cells to the surroundings

A hypotonic solution has a higher level of solutes so the water moves out of the cells to the surroundings

The salt and water solution in the potato is a hypotonic solution

Osmosis is the movement of large molecules across a membrane which require embedded proteins

The plain water in this experiment is the solvent and the salt is the solute.

Passive transport requires no energy and the molecules move with the concentration gradient or from high concentration to low concentration

Active transport required no energy and the molecules move with the concentration gradient or from high concentration to low concentration.

The water on the inside of the potato with the salt molecules is an isotonic solution the same as the solution on the outside of the potato.

Water will not move by simple diffusion (osmosis) into or out of cells it requires energy or protein transporters

The solution of salt water in the potato has a lower concentration of water molecules so the water on the outside should move into the cells

True or False: The solution of salt water inside of the hollowpotato has a lower concentration of water molecules so the water onthe outside of the potato should move into the potato cells. Or thewater molecules inside of the grape or pea will move to the outsidewhere there are fewer water molecules and more salt.

True or False: The water on the inside of the potato with thesalt molecules is an isotonic solution the same as the solution onthe outside of the potato.

True or False: Water will not move by simple diffusion (osmosis)into or out of cells it requires energy or proteintransporters.

T or F The salt and water solution inside of the hollow potatois a hypotonic solution.

T or F: Osmosis is the movement of large molecules across a semipermeable membrane which require embedded proteins.

T or F The plain water in this experiment is the solvent and thesalt is the solute.

T or F Active transport requires no energy and the moleculesmove with the concentration gradient from low concentration to ahigh concentration.

T/F Passive transport requires no energy and the molecules movewith the concentration gradient or from high concentration to lowconcentration

T/F A hypotonic solution has a higher level of solutes so thewater moves out of the cells to the surroundings.

T/F A hypertonic solution has a higher level of solutes so thewater moves out of the cells to the surroundings.

Why does a slug die when you put salt on her/him? (Think aboutwhat happened in this lab) :

A. The salt on the outside of the slug causes the water frominside of the cells to move out of the cells. The dehydration ofthe slug causes death

B. The slug does not die but becomes enlarged from the movementof water into the slug cells caused by a hypertonic solution

C. The salt and moisture on the outside of the slug cause anisotonic state and the water leaves the slug quickly byosmosis.

D. Sigh. The poor slug, sacrificed for science by many youngnature lovers around the world. Obviously this happens as theoutside solution is hypotonic and the inside of the slug's cellsare hypertonic. Energy is used for active transport leading toosmosis.
