Understanding Turgor Pressure in Plants

Turgor pressure is the pressure exerted by the water inside plant cells on the cell walls, which helps to maintain the shape of the cell and support the plant's structure. It is caused by the movement of water into the cell through the process of osmosis, where water molecules pass through the cell membrane from a region of high concentration to a region of low concentration.

When a plant is exposed to drought or other conditions that cause water loss, the cells can lose water and shrink, leading to a decrease in turgor pressure. This can cause the plant to wilt or become limp, as the cell walls are no longer supported by the pressure of the water inside the cells.

On the other hand, if a plant is exposed to too much water, the cells can become waterlogged and the turgor pressure can become too high, causing the cells to burst and leading to damage or death of the plant.

So, turgescing is the process of increasing turgor pressure in plants, which can help them to survive drought conditions by maintaining the water content of the cells and supporting the plant's structure.
