No more flea bites
There are thousands of tiny atoms living in one cell. Because a cell is mostly made up of water, there are typically more water atoms than any other type of atom.
No, fleas are multicellular organisms composed of eukaryotic cells, not prokaryotic cells. Eukaryotic cells are typically more complex, with membrane-bound organelles and a nucleus that contains the organism's genetic material.
You are correct. A hypertonic solution is a solution outside the cell that has more solute in it that water. This means that there is more water inside the cell than solute. Because there is more water in the cell, it will diffuse out of it and the cell will shrivel up.
Osmosis the transfer of water through the cell. So when in osmosis the cell needs more water.
Water is made up of one molecule. A molecule of water is made of two atoms of hydrogen and one atom of oxygen. Water is usually written as H2O; but HOH is more chemically correct. Think of water as partially burnt hydrogen.
It would depend on what is in the water. If there is more sodium (Na) in the water than in the cell, water will move out of the cell. The cell will become limp or crenate. If the opposite is true, the cell will swell and could burst. A good rule of thumb is "water follows salt (NaCl)". This means that wherever there is more salt, water will follow.
When there's more water outside the cell than inside, water will move into the cell through a process called osmosis. This occurs because water tends to flow from areas of lower solute concentration (more water) to areas of higher solute concentration (less water) to achieve equilibrium. As a result, the cell may swell and potentially burst if the influx of water is excessive.
The cell will be very turgid and stiff.

If a cheek cell is surrounded by pure water, more water would move into the cell. This is due to osmosis, where water moves from an area of lower solute concentration (the pure water) to an area of higher solute concentration (inside the cell). As a result, the cheek cell may swell or even burst if the influx of water is excessive.
The plant cell sap is more concentrated than the water in the cell because it contains a variety of solutes such as sugars, ions, and proteins dissolved in the water. This higher solute concentration in the cell sap creates a hypertonic environment compared to the surrounding water inside the cell.
