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.

Osmosis (endo-osmosis to take water inside plant cell)
You can observe osmosis in plant cells by placing a plant cell in a hypertonic or hypotonic solution and observing any changes in cell size and shape due to the movement of water. Hypertonic solution will cause cell to shrink (plasmolysis) and hypotonic solution will cause cell to swell. You can use a microscope to observe these changes in plant cells during osmosis.
Plant cells have a strong rigid cell wall on the outside of the cell membrane. This stops the cell bursting when it absorbs water by osmosis. The increase in pressure makes the cell rigid. This is useful as plants do not have a skeleton. Instead the leaves and shoots can be supported by the pressure of water in their cells. If plant cells lose too much water by osmosis they become less rigid and eventually the cell membrane shrinks away from the cell wall.
A plant cell becomes flaccid when there is a loss of water due to osmosis. This loss of water causes the cell to shrink and lose turgor pressure, resulting in a lack of firmness or rigidity. Flaccidity can be reversed by rehydrating the cell.
Osmosis brings water into the cell which helps wilted plants recover from dehydration.
it is for the absorption of water (by osmosis) and ions into the cell for photosyntesis
The plant cell absorbs water by simple diffusion and osmosis.
