What happens to an Elodea cell if you put it into 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.
What type of solution was the Elodea placed in?
The Elodea cells have been placed in a 10% NaCl solution. The contents of the cells have been reduced to the spherical structures shown. Animal cells placed in a hypertonic solution will undergo crenation, a condition where the cell shrivels up as it loses water.
What happens to an Elodea leaf in a hypotonic solution?
Thus, a hypotonic solution has more water than the cell and water has a tendency to move (diffuse) into the cell. Placing Elodea cells into 100% water, which is more hypotonic than freshwater, also causes water movement into of the cells resulting in the swelling of the cells.
What happens to Elodea in isotonic solution?
Elodea cells would have no change in solution that is isotonic to the cell, water will diffuse in and out of cell equally.
When Elodea was placed in a hypertonic solution what occurred in the cell quizlet?
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.
When Elodea are placed in a hypertonic environment plasmolysis will occur this means that?
If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cell shrink and crumple.
What is happening at the cellular level to the Elodea cells when mounted in a solution of distilled water?
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.
Why are Elodea cells not isotonic distilled?
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.
Are Elodea cells isotonic?
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 is your hypothesis for this experiment Elodea cells?
What was your hypothesis for the “Tonicity in Elodea Cells” lab? The Elodea placed in a hypertonic solution will shrink because osmosis will draw water out of the cells, causing their volume to decrease.
What happens to cells that are placed in isotonic hypertonic and hypotonic solutions?
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
What happens if a plant cell is placed in a hypotonic solution?
If placed in a hypotonic solution, water molecules will enter the cell, causing it to swell and burst. Plant cells (bottom panel) become plasmolyzed in a hypertonic solution, but tend to do best in a hypotonic environment.
