When plant cells are placed in salt water, they experience a process called osmosis, where water moves out of the cells to the area with higher salt concentration outside. This leads to a loss of turgor pressure, causing the cells to shrink and become plasmolyzed. As a result, the plant may wilt and exhibit signs of dehydration. If the exposure to salt water continues, it can ultimately damage the cells and lead to plant death.
What else can I help you with?
When can tell that plant cells are undergoing osmosis without using a scale?
You can tell that plant cells are undergoing osmosis if they swell or shrink. When plant cells are placed in a hypertonic solution, they lose water and shrink. Conversely, when they are placed in a hypotonic solution, they gain water and swell. These changes in cell size indicate that osmosis is occurring.
Why does a plant cell lose water by osmosis when put in a concentrated solution?
Not just plant cells, all cells with semi-permeable membranes loose water when placed in a more highly concentrated solution.
Suppose the test tube contained plant cells instead of red blood cells what will happened if the cells were placed in water with very little salt?
If the plant cells were placed in water with very little salt, they would undergo a process known as plasmolysis. Plasmolysis is the shrinking of the cell membrane away from the cell wall due to water loss. This occurs because the water concentration outside the cells is higher than inside, causing water to move out of the cells, leading to wilting and potential cell damage.
What happens to plant cells not in distilled water?
When plant cells are not in distilled water, they may experience different effects depending on the surrounding solution's concentration. If placed in a hypertonic solution (higher solute concentration), water will exit the cells, leading to plasmolysis, where the cell membrane pulls away from the cell wall. In a hypotonic solution (lower solute concentration), water will enter the cells, potentially causing them to swell and become turgid. In isotonic conditions, there would be no net movement of water, and the cells would maintain their normal shape and function.
What happens to the plant cells once they are placed in the growth medium?
Once plant cells are placed in the growth medium, they begin to absorb nutrients and water, which facilitates their growth and division. The optimal conditions in the medium, such as pH and temperature, encourage cellular metabolism and can stimulate the production of hormones necessary for growth. As a result, the cells can differentiate and develop into various plant tissues, ultimately forming new shoots, roots, or whole plants, depending on the medium's composition and conditions.
What happens to the plant cells when pure water is added?
Because there is more salt in the plant cells, when they are placed in pure water (with no salt), water will move into the cells in an effort to balance the concentration inside the cell and out the cell. The plant cells will become enlarged with water and may burst. This is a way to make wilted celery to become like it did when it was bought.
What happens to plant cells when placed in a hypotonic solution?
When a plant cell is placed in an hypotonic solution it becomes swollen and hard. The cell takes in water by osmosis and starts to swell, but the cell wall prevents it from bursting.
What term describes the condition of plant cells after being placed in distilled water?
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.

What happens to the cells when they are placed into distilled water?
When cells are placed in distilled water, they are exposed to a hypotonic environment, meaning the concentration of solutes outside the cell is lower than inside. As a result, water enters the cells through osmosis, causing them to swell. If the influx of water continues, the cells may eventually burst or lyse, especially if they lack a rigid cell wall, as in animal cells. Plant cells, on the other hand, may become turgid but usually do not burst due to their cell wall, which provides structural support.

What happens to plant cells when you put salt water on them?
When plant cells are exposed to salt water, water moves out of the cells through osmosis, causing the cells to lose turgor pressure and shrink. This process is known as plasmolysis. Continued exposure to salt water can eventually lead to the death of the plant cells.
Which diagram best illustrates how these plant cells will appear after they are placed in a solution having a greater water concentration than the cells have?
When plant cells are placed in a solution with a greater water concentration (hypotonic solution), water will enter the cells through osmosis. This causes the cells to swell and become turgid, as the central vacuole fills with water, pushing the cell membrane against the cell wall. The diagram that best illustrates this scenario would show the plant cells enlarged and firm, with the cell membrane pressed against the rigid cell wall, indicating turgor pressure.
What are flaccid cells?
Flaccid cells are plant cells that lack turgor pressure, causing them to become limp and wilted. This can be due to a lack of water or a disruption in the osmotic balance within the cell. Flaccid cells can impact the overall structure and function of the plant.
