Osmosis is the diffusion of water across a semi-permeable membrane, like a cell wall. Cell walls in plant cells are semi-permeable, allowing water to move in and out of the cell through osmosis to help maintain the cell's turgor pressure and overall structure.
Osmosis primarily occurs in the symplast pathway, as water moves through the living cells of the plant via plasmodesmata. The apoplast pathway, which involves movement of water through the cell walls and intercellular spaces, does not involve osmosis because osmosis requires a selectively permeable membrane, which is absent in the cell walls.
In bacteria, fungi, and plants, the high internal pressure generated by osmosis is counteracted by the mechanical strength of their cell walls. These cell walls provide structural support and help prevent the cells from bursting due to the osmotic pressure.
Living cells with cell walls regulate water balance through the process of osmosis, where water moves in and out of the cell to maintain equilibrium. Cells without cell walls regulate water balance mainly through ion channels and transporters in their plasma membranes that help control the movement of water and solutes.

The vacuole is the organelle in a plant cell that is involved in osmosis. It helps maintain turgor pressure in the cell by regulating the movement of water molecules in and out of the cell through osmosis.

Plants with rigid cell walls are unable to do phagocytosis because this process involves cell engulfment of large particles, which is hindered by the rigidity of the cell wall. Diffusion, osmosis, and active transport can still occur in plants with rigid cell walls as these processes involve movement of particles across membranes.
Plants have cell walls that prevent them from dessication (water loss). Animals lack cell walls because of nutritional requirements that need to enter the cell via diffusion or osmosis.

Yes. Organisms use osmosis to absorb nutrients across cell walls.

Osmosis is important to cell functions because it keeps the cell alive
Turgor pressure forces plasma membrane against cell walls of plants and bacteria. The pressure is caused by osmosis.

It depends on the organism. Osmosis can be prevented by the cells if the concentration of solute inside the cell is the same as that of the concentration outside the cell. There is no "perfect" way to prevent osmosis apart from cell walls; even marine organisms can swell up and burst if you place them in a concentration that is different from their normal surroundings. Take saltwater aquarium fish for example.
Alcohol moves across the cell membrane by means of osmosis.
The diffusion of water through a cell membrane is called osmosis.
