In a wilted plant- the wilted plant becomes firm again.

Osmosis in plant cells. (water moves into plant cells by osmosis). Osmosis in animal cells. (water also diffuses in and out of animal cells by osmosis). Hope this answers your question.
Osmosis is important to cell functions because it keeps the cell alive
by endo-osmosis
if the membrane is intact and there is a change of concentration of solut or solvent, osmosis should happen.
plants absorb water and nutrients through osmosis. Therefore when there is no osmosis plants cannot survive.
When a wilted plant is watered, osmosis occurs as water moves from the soil, where it is in higher concentration, into the plant's cells, which have a lower concentration of water. This process causes the plant's cells to swell, increasing turgor pressure and leading to the re-inflation of the plant's tissues. As a result, the wilting is alleviated, and the plant regains its upright posture and vitality.
You can tell that plant cells are undergoing osmosis if they swell or shrink. When plant cells are placed in a hypertonic solution, they lose water and shrink. Conversely, when they are placed in a hypotonic solution, they gain water and swell. These changes in cell size indicate that osmosis is occurring.
Osmosis occurs in both animal and plant cells across their semi-permeable membranes. In animal cells, water moves in and out through the plasma membrane to maintain osmotic balance, affecting cell shape and volume. In plant cells, osmosis primarily occurs in the vacuole, where water influx creates turgor pressure, helping to maintain structural integrity. Both cell types rely on osmosis to regulate their internal environments and ensure proper function.
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.
Osmosis (endo-osmosis to take water inside plant cell)
Osmosis moves water into the central vacuole which then presses against the cell wall to create turgor pressure, causing the plant stems to become rigid.
