the elodea cells swell and the cell becimes fat and dies
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.
you would not see the same effect because there is sugar in one and not in the other
Elodea cells are smaller
No. An elodea is a species of aquatic plant.
The lower epidermis of the elodea leaf has the largest cell.
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.
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.
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 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).
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.
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.
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.

Elodea is an aquatic plant.
nothin elodea dont have no plants
Is Elodea cell an organism?
The purpose of the experiment is to demonstrate the process of photosynthesis. When the elodea plant is added to the yellow solution (indicating acidity), it will consume carbon dioxide and release oxygen through photosynthesis. This will cause a color change in the solution from yellow to blue as the pH increases due to the removal of carbon dioxide.
