When an Elodea leaf is placed in a drop of distilled water, the plasma membrane can be observed as a thin line just inside the cell wall. The cell wall provides structural support, while the plasma membrane regulates the movement of substances in and out of the cell. In a hypotonic environment like distilled water, water enters the cell, causing it to swell and the plasma membrane to press against the cell wall. This can make the plasma membrane more visually distinct under a microscope.
Elodea is placed in both flasks to show how aquatic plants release oxygen during photosynthesis. By comparing the presence of bubbles in the light and absence of bubbles in the dark, one can observe the effect of light on the process of photosynthesis in Elodea.
do you go to UTAS? that is not an answer how is this going to help people ????
Yes, because the distilled water has higher water potential as compared the the strip potato, so water will enter the potato by osmosis, through a partially permeable membrane, causing it to increase in size (:
It expands. Get bigger over a period of time.
The distilled water is a hypotonic environment.
If the vacuoles in Elodea leaf cells are placed in distilled water, they become hypotonic. Distilled water has a lower solute concentration compared to the vacuoles of the cells, causing water to move into the cells through osmosis, leading to swelling and eventual bursting of the cells.

Plasmolysis describes the condition of plant cells after being placed in distilled water. In plasmolysis, water exits the cell by osmosis, causing the cell membrane to detach from the cell wall. This results in the cell shrinking and the cytoplasm pulling away from the cell wall.
Distilled water has a lower concentration of solutes compared to a solution, causing it to be hypotonic. When placed across a semipermeable membrane from a solution with a higher solute concentration, water will move through osmosis from the distilled water side to the solution side. This will result in an increase in the volume of the solution as water moves into it.
The scientific term for the appearance of elodea cells when placed in a hypotonic solution is turgid. This occurs when water moves into the cell causing it to swell and become firm.
The hypothesis of an osmosis lab with an Elodea leaf could be that the Elodea leaf will lose water and shrink when placed in a hypertonic solution due to water moving out of the leaf cells by osmosis, causing the cells to become flaccid. Conversely, if the Elodea leaf is placed in a hypotonic solution, it may gain water, swell, and become turgid as water moves into the leaf cells via osmosis.

no changes
eat cholate
Salt water is a hypertonic solution; therefore, the vacuole in the cell will shrink. The water in the cell's vacuole exits the plasma membrane to balance the solutions, and since the salt can not enter through the cells differentialy permeable membrane the cell is only loosing substance so it shrinks. When the elodea cells are in fresh water there is no reaction. Elodea is a fresh water plant
