What happens to an elodea leaf when added a phenol red solution?
When an Elodea leaf is added to a phenol red solution, the leaf will release oxygen through photosynthesis. The oxygen will cause the phenol red solution to change color, indicating the presence of oxygen production.
What happens to an elodea cell when the leaf is mounted in regular tap water?
When an Elodea leaf cell is mounted in regular tap water, it generally experiences a state of turgor pressure. The water enters the cell through osmosis, causing the central vacuole to swell and push the cell membrane against the rigid cell wall. This results in a firm and turgid cell, which helps maintain the structural integrity of the plant. If the water is hypotonic, the cells will remain healthy; however, if the water is excessively saline or has other impurities, it could lead to plasmolysis.
What would happen with elodea in an isotonic solution?
In an isotonic solution, the concentration of solutes outside the elodea cells is equal to that inside the cells. As a result, water movement into and out of the cells occurs at equal rates, leading to no net change in cell volume. The elodea will maintain its turgor pressure and remain rigid, as the cells are neither gaining nor losing water. Overall, the plant will appear healthy and unaffected by osmotic pressure changes.
Would you see the same effect in elodea cells if you used a glucose solution instead of a water solution?
you would not see the same effect because there is sugar in one and not in the other
Would you see the same effect in the elodea cells if you used a glucose solution Instead of salt water solution?
If you used a glucose solution instead of a saltwater solution on Elodea cells, the effect would likely differ due to the osmotic properties of the solutions. Saltwater is hypertonic to the cells, causing water to leave the cells and leading to plasmolysis. In contrast, a glucose solution may be isotonic or even hypotonic, which could maintain or increase turgor pressure in the cells, preventing plasmolysis and potentially resulting in healthier, more turgid cells.

What happens to elodea cells mounted in salt solution?
Oh, dude, when you stick elodea cells in a salt solution, they're like, "Whoa, this is salty!" The salt solution messes with their osmotic balance, so water leaves the cells, making them shrink and look all sad. It's like when you eat too many chips and your fingers swell up – not a good time for anyone involved.
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.
When the elodea leaf is moved from salt solution n placed back in water what happens to the cells?
When you deal with problems like this, you need to consider diffusion and osmosis. In this case, you would refer to diffusion, which is the movement of water across a membrane from high concentrations to low concentrations (to try to balance the concentrations). First consider what happens to the cells when you place the elodea leaf in the salt solution; the water in the cells tries to balance the high concentration of salt (sodium chloride) in the surrounding solution, so the water leaves the leaf, thus the cells shrink. Now when you put the elodea leaf into regular water again, there is a higher concentration of water in the surrounding environment compared to inside the leaf's cells, so in attempt to balance concentrations, water goes INTO the cells, thus the cells in the elodea leaf swell (expand).
What is the hypothesis of osmosis lab elodea leaf?
The hypothesis of an osmosis lab with an Elodea leaf could be that the Elodea leaf will lose water and shrink when placed in a hypertonic solution due to water moving out of the leaf cells by osmosis, causing the cells to become flaccid. Conversely, if the Elodea leaf is placed in a hypotonic solution, it may gain water, swell, and become turgid as water moves into the leaf cells via osmosis.
What would cause the blue btb solution containing elodea to turn green?
The blue BTB solution turning green in the presence of elodea indicates that photosynthesis is taking place. During photosynthesis, elodea utilizes carbon dioxide and water to produce glucose and oxygen, leading to a change in the color of the indicator solution from blue to green.

Do Elodea cells have starch?
if starch is present in a substance, the solution IKI when combined will turn the substance a blue-black color. When the plant Elodea was combined with IKI the elodea did not turn a blue-black color. Hence elodea does not contain starch.

Is Elodea aquatic or terrestrial?
Elodea is an aquatic plant.
Does Elodea have predators?
nothin elodea dont have no plants
