because it is already green when you look at it so if you stain it, say with methylene blue, the color will change and you will not be able to recognize some of the structures in the cell like you would without it being stained.
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 human epithelial cells are thick and boxlike whereas elodea cells are thin and platelike. The cells of elodea are rigid and rectangular in shape.
A wet mount slide is typically used to view an Elodea leaf under a microscope. This type of slide allows the leaf to remain in a hydrated state, which is important for observing its cellular structure and processes.
Elodea is an aquatic plant commonly known as waterweed. It belongs to the genus Elodea within the family Hydrocharitaceae. Elodea is often used in biology classrooms for studying plant cells and photosynthesis.
Elodea leaf cells have chloroplasts, which are responsible for photosynthesis, a process that converts light energy into chemical energy. This is a unique organelle not found in animal cells. The central vacuole in Elodea leaf cells helps maintain turgor pressure, providing rigidity to the cell and aiding in photosynthesis, another feature not typically found in animal cells.
The lower epidermis of the elodea leaf has the largest cell.
They are purple in color. So there is no need

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.
An Elodea leaf belongs in the domain Eukarya, as it is a complex, multicellular organism with cells that contain a true nucleus.
The reason for this is that many cells have organelles that are very hard to see under a microscope, staining these cells allows you to more easily see these organelles. In the case of an Elodea, the invisble organelles is the central vacuole.
The human epithelial cells are thick and boxlike whereas elodea cells are thin and platelike. The cells of elodea are rigid and rectangular in shape.
Due to plasmolysis
A wet mount slide is typically used to view an Elodea leaf under a microscope. This type of slide allows the leaf to remain in a hydrated state, which is important for observing its cellular structure and processes.

When an elodea leaf is mounted on a 10 percent salt solution, the cells of the leaf will lose water through osmosis. This will cause the cells to shrink and the leaf to become flaccid. The high salt concentration outside the cells will create a hypertonic environment, leading to water moving out of the cells to try to balance the concentration of solutes.
