What will happen to Elodea cells when placed in a saltwater solution?

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. Such cells are said to be plasmolyzed. Therefore, if it were placed in a hypertonic solution it would lose water and shrivel.

What happens when plant cell is placed in salt solution?

When a plant cell is placed in concentrated salt solution, water concentration inside the cell is greater than that which is outside the cell. Therefore, water moves through the cell membrane into the surrounding medium. The cell then swells to become turgid. It is called deplasmolysis.

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.

What happens to the Elodea cells in an isotonic solution?

A hypertonic solution will cause a cell to lose water through osmosis since the solution will have a higher solute concentration than the inside of the cell. An isotonic solution will cause no net water gain/loss since the solute concentration between the cell and solution will be equal.

What happened to the Elodea cell in 20% NaCl Why?

Terms in this set (9) What will happen to elodea cells when you add 20% NaCl? They will undergo “plasmolysis”. Because the NaCl solution is very hypertonic to the cells, water will undergo a net movement OUT of the cell, and the cell will shrivel and pull away from the cell wall.

What is the function of the Elodea cell?

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). The central vacuole takes up most of the volume of the cell.

Why do cells look different in salt solution?

When the plant cells are placed in the salt solution, there is a higher concentration of water molecules in the cell and a lower concentration of water in the salt solution and thus a concentration gradient has been set up.

What happens to cells in salt solution?

Salt water is a hypertonic solution in comparison to the internal cellular liquid, since there are more solute particles outside in the salt water than inside in the cytoplasm. This means that water will move out of the cells by osmosis due to the concentration gradient, and the cells will become shrivelled.

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.

What would you need to do to reverse plasmolysis in the Elodea cells?

Plasmolysis can be reversed if the cell is placed in a hypotonic solution. Stomata help keep water in the plant so it does not dry out. Wax also keeps water in the plant. The equivalent process in animal cells is called crenation.

When Elodea leaves were placed in 10% NaCl What was the result?

Terms in this set (21) 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.

What structures are visible in the Elodea leaf cells?

Some plant cells have organelles called chloroplasts that make them green and able to capture energy from light. Rigid walls typically made of cellulose surround plant cells. Chloroplasts and mitochondria move within Elodea leaf cells; nuclei are also visible as clear, fried-egg-shaped structures.

What happens to Elodea cells when it gets put in salt water?

Explain (in terms of water potential) the observations made when the Elodea was placed in a salt solution. 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.

Is Elodea a freshwater or salt water plant?

Elodea normally lives in fresh water . What changes would you observe in the cells of an Elodea plant that was suddenly moved from fresh water to salt water? Why? How would plasmolysis affect the entire plant?

How does a cell react in salt water?

If there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size , swelling up as the water fills the cell in its imperative to combine with the salt. If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it.

What is the domain of Elodea?

Elodea is a kingdom Plantae , also a domain Eukarya and since it is a plant cell, it will have a cell wall, a nucleus and other important organelles such as a large central vacuole which will occupy most of the cell (Reece et al., 2014). These have more complex cell structures compared to domain bacteria or domain archaea.
