Heya ✌️

Osmosis is extremely important in all processes in which water moves into and out of cells, because all living cell membranes are semipermeable. Osmosis keeps the amount of water in all the cells of an animal or a plant approximately equal and helps to prevent certain cells from drying out. Water is drawn from the soil into the roots of a plant by osmosis. When there is an adequate water supply, osmosis helps to prevent the wilting of plants that is caused by loss of water.

The effect of osmosis in a root is shown in the accompanying illustration. A hole, one inch (2.5 cm) deep, is cut into the top of the carrot and nearly filled with a concentrated solution of sugar and water. The carrot is then placed in a glass of water with its top one-half inch (1.3 cm) above the surface. Within a few hours, water from the glass will be drawn into the hole by osmosis. The level of the solution in the hole will rise until the solution overflows.

Osmosis is the diffusion of water and if water diffuses into a plant cell then the cell swells and is turgid, thus supporting the plant

when water leaves the cell (there isn't enough water in the plant) the cell becomes flaccid and if this happens in excess the cell shrivels and can support itself ("welts")

hope it helps :)
