What happens to a plant cell when it is placed into distilled water?
When the Plant cells are dipped in distilled water it will become turgid because distilled water has a very less amount of solutes and a high concentration of solvent so it is considered as a hypotonic solution as compared to the intracellular environment, in other words, we can say that the solute concentration of the …
What happened to the Elodea cells when you added distilled water to the slide vs the 10% NaCl?
distilled water? On the Elodea cells the 10% NaCl solution causes the cell membrane to shrink but the cell wall of plants prevents the entire cell from shrinking. Because of this the cell appears to have the chloroplasts clustered in the center. No change, because the solution was isotonic.
Why is Elodea prepared using saline?
The 0.9% saline solution used to submerge the elodea cells is a hypertonic solution; as such, water from within the plant cell crossed the cell membrane in order to restore equilibrium per the mechanics of osmosis. Unlike an animal cell, the rigid plant cell wall does not allow the entire cell to shrink.
What do you think would happen if you moved an Elodea plant from your freshwater aquarium to a saltwater aquarium?
Answers to questions When the Elodea was placed in the salt solution, the vacuoles disappeared and the protoplasm came away from the cell wall making the organelles appear to be clumped in the middle of the cell. Therefore, if it were placed in a hypertonic solution it would lose water and shrivel.
What happens when elodea is placed in distilled water?
This video shows the Elodea being “rehydrated” with distilled water. The chloroplasts are spread throughout the cell both before the salt solution, and after the distilled water is put onto the slide. Distilled water represents a hypotonic solution, yet the cells do not burst because of the cell wall.
Do plant cells shrink when placed in distilled water?
(d) The cells shrink. Distilled water is hypotonic as compared to a cell. Complete answer: When cells are placed in distilled water, water moves from outside the cell to the inside.

Why do Elodea cells shrink in salt water?
When the salt solution is added, the salt ions outside the cell membrane cause the water molecules to leave the cell through the cell membrane causing it to shrink into a blob in the centre of the cell wall. The movement of water molecules is called osmosis.
Can Elodea live in brackish water?
More and Less Brackish Water Aquarium Plant Species: You’ll likely be surprised at how many common aquarium plants are to some degree brackish. Most all do tolerate salts to some extent. ” Anacharis”, actually members of the genera Egeria, Elodea are either the most common species of aquarium plant or close to it.
Do Elodea cells have a cell wall?
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane.
Why do plant cells not burst when placed in distilled water?
As the plant cell is placed in distilled water then the movement of water occurs inside the cell by osmosis, the cell becomes turgid. The pressure exerted by the cell wall prevents the cell from bursting.
