When a salt solution is added to plant cells, the guard cells typically lose water through osmosis due to the higher solute concentration outside the cells. As they lose water, the guard cells become flaccid and change shape, causing the stomata to close. This response helps the plant reduce water loss in a saline environment. Consequently, the overall turgor pressure in the guard cells decreases, leading to a more collapsed appearance.

What is the differences in the appearance of the cells in concentrated salt solution compared with the cells in distilled water?
In a concentrated salt solution, cells typically undergo plasmolysis, where water exits the cell, causing the cell membrane to pull away from the cell wall and resulting in a shriveled appearance. In contrast, cells in distilled water swell due to osmosis, as water enters the cells, making them turgid and plump. Therefore, cells in a concentrated salt solution appear shrunken and wrinkled, while those in distilled water appear swollen and firm.
What is an example of Crenation?
An example of crenation is when red blood cells lose water and shrink in a hypertonic solution, such as saltwater. This causes the cells to have a scalloped appearance due to the contraction of the cell membrane.
Test tube contains red blood cells and a salt solution When the tube is held up to a page you cannot see the print with reference to a concentrationof 0.9 percent how concentrated is the?
The concentration of the salt solution is 0.9%, which is isotonic with red blood cells. This means that there is no net movement of water across the cell membrane, resulting in no change in the appearance of the red blood cells when viewed against a page.
What happens when solution of salt or sugar is put on mounted Rhoeo leaf?
When a solution of salt or sugar is put on a mounted Rhoeo leaf, the process of osmosis occurs. Water moves from an area of higher concentration (inside the leaf) to an area of lower concentration (the solution outside the leaf), causing the leaf cells to shrink or swell depending on the concentration of the solution. This can disrupt the normal functioning of the leaf cells and lead to changes in their appearance.
What happens to a cell plant cell or animal cell when placed in following solution a hypotonic solution b isotonic solution c hypertonic solution?
When placed in an isotonic solution (i.e. a solution where the concentration of water molecules is roughly equal to the that within cells), there is equal diffusion of water into and out of the cells. Therefore, the cells find this environment suitable. In a hypotonic solution (i.e. a solution where the concentration of water molecules is much more than that within cells) water diffuses into cells as a result of which the cells swell. Excessive swelling causes the cells to burst, a phenomenon called cell lysis In a hypertonic solution (i.e. a solution where the concentration of water molecules is lesser than that within cells) water moved out from within cells to the surrounding medium. As a result of this, cells shrink.
What is the scientific term for the appearance of elodea cells placed in a hypotonic solution?
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.

What appearance will red blood cells have when they are placed in 90 percent NaCI?
9% NaCl is a hypertonic saline solution. Red blood cells will appear to shrink as they lose water out of the cell membrane and into the saline solution.
What appearance will red blood cells have when they are placed in 9 percent NaCl?
Since a 9% saline solution is hypertonic as compared to the cell, it would crenate (crush or shrink).
What would happen to cells tested with iodine solution?
Cells that contain starch will turn blue-black when tested with iodine solution, indicating the presence of starch. Cells without starch will not change color in the presence of iodine solution. This test is commonly used to identify the presence of starch in cells.
Is a measure of a solution's ability to change the volume of cells by altering their water content?
tonicity
Where can you access all formatting options for worksheet cells?
You can format the appearance of individual cells by modifying the alignment of text within the cell, indenting cell text, or adding borders of different styles and colors to individual cells or ranges.
What is an example of Crenation?
An example of crenation is when red blood cells lose water and shrink in a hypertonic solution, such as saltwater. This causes the cells to have a scalloped appearance due to the contraction of the cell membrane.
What is a measure of a solutions ability to change the volume of cells by altering their water content?
Osmotic potential is a measure of a solution's ability to change the volume of cells by altering their water content. It is influenced by the concentration of solutes in a solution, affecting the direction of water movement into or out of cells. This process is vital for maintaining cellular homeostasis in organisms.

The concentration of the salt solution is 0.9%, which is isotonic with red blood cells. This means that there is no net movement of water across the cell membrane, resulting in no change in the appearance of the red blood cells when viewed against a page.
What is the function of adding iodine solution to the temporary mount?
Adding iodine solution to a temporary mount is used to stain and increase visibility of cellular structures like cell walls, nuclei, and starch grains. It helps highlight specific features under a microscope by reacting with components in the cells, aiding in their identification and study.
What effect did staining with iodine solution have on the cells?
Staining with iodine solution caused the cells to change color based on the presence of starch. Starch-containing cells turned blue-black, while cells lacking starch remained unchanged. This allows for easier visualization and differentiation of cell types under a microscope.
