What would happens if you put Elodea in salt water?
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.
Does Elodea grow in salt water?
The Elodea plant which normally lives in low salt now finds itself in high salt. Water will move OUT of the plant, moving from low salt to high salt. This is plasmolysis. The cell membrane pulls away from the cell way.
Does salt affect Elodea?
Moreover, Elodea species were more sensitive to salt in spring, during the growing season. It has been shown that one salt supply had a stronger impact on morphological traits than three salt supplies regularly provided during the time of the experiment.
What do you think would happen to the cells if we put the Elodea in a distilled water solution?
This picture shows normal Elodea. 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.
What happens when elodea is placed in a hypertonic solution?
Elodea cells, when placed in a hypertonic solution, will lose water through osmosis. This will make them flaccid. The central vacuole reduces and eventually disappears. The cell membrane pulls away from the cell wall and the organelles appear concentrated at the center of the cell.
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.
Can Elodea live in brackish water?
What scientific term is used to explain what occurred to the Elodea cells in the salt solution?
Plasmolysis is the shrinking of the cytoplasm of a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution. During plasmolysis, the cell membrane pulls away from the cell wall. This does not happen in low salt concentration because of the rigid cell wall.
What happens when Elodea is placed in a hypertonic solution?
What happened to the Elodea leaf when you added salt water to the slide?
By adding salt water to the Elodea cell environment, students will observe the process of plasmolysis, shrinkage of the cell contents due to water loss.
When testing tonicity in Elodea cells once Elodea cells were placed in distilled water what did you observe?
The hypertonic 10% NaCl solution produced the shrunken Elodea cells as the water left the vacuole and the hypotonic distilled water solution produced the swollen Elodea cells as the water filled the vacuole. Crenation happens in animal cells.
