Several factors can affect osmosis in plants, including:

Without osmosis, the plant cannot regulate its own temperature or exchange gases. It would either suffocate (never opening) or dry out (never closing).

| Function | Osmotic Role | | :--- | :--- | | | Draws water from soil into root hairs. | | Ascent of Sap | Creates root pressure and facilitates transpiration pull. | | Turgor | Fills vacuoles to keep stems and leaves erect. | | Stomata | Opens/closes guard cells to regulate gas and water. | | Movement | Triggers rapid pressure changes in specialized cells. |

Once inside the outer root cells, water continues to move inward through the plant’s tissues, cell by cell, until it reaches the xylem (the plant's internal "plumbing"). 2. Creating Turgor Pressure (The Plant's "Skeleton")
