What type of organism is an elodea?
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.
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 layer of a elodea leaf are the cells in?
You have asked "how many cell layers are there in an Elodea cell". Obviously a cell cannot contain layers of cells so your original question is nonsense. What you should have asked is "how many cell layers are there in an Elodea leaf?". Read it again. Think about it. Think until it hurts then think some more. It's not my fault you can't see them. If you have as much trouble seeing what's there as you seem to have reading what you've written I'm not surprised. The way to see two layers of cells is to focus on one layer and then change the focus so that the other layer comes into view. To show there are two layers by continually altering the focus in ONE direction only you should be able to move through the sequence:- no layer in focus > one layer in focus > other layer in focus > no layer in focus
Do elodea cells contain nucei?
Yes, elodea cells contain nuclei. Nuclei are membrane-bound organelles that contain the genetic material of the cell, including DNA. In plant cells, the nucleus is typically located in the center of the cell.
Is elodea multicellular or unicellular?
Elodea is a Eukaryote. Prokaryotic consists of bacteria whereas Eukaryotes are plants and animals. Eukaryotes have a nucleas, Prokaryotes do not.
Why didnt we stain the elodea leaf?
They are purple in color. So there is no need

Why don't you have to stain the elodea leaf cell?
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.

Do bacteria have vacuoles and if so please specify by saying how small or large?
No, they do not because they are prokaryotic cells. some do have vacuole like the gas vacuole used for buoyancy.
What cell contains the cell sap?
In fully grown plant cells, there is a large central space surrounded by a membrane called vacuole. This vacuole ia permanent feature of the cell. This is filled with a liquid called cell sap. So the cell sap is in the vacuole.
What is the vacule in a animal?
Do you mean vacuole? if so, then in an animal cell, they are organelles that store water and nutrients. In an animal cell there is usually a few small vacuoles. In a plant cell, there is one large one called the large central vacuole.
What kind of cell is found in a vacuole?
Central vacuoles are often found in plant cells. Plants need lots of water, and plants store water, so they have a large vacuole.

Can guppies survive off elodea?
They are omnivores so the answer is no.
