Water Transport in Plants

The pathway is the non-living pathway, and the reason is the adhesion of water molecules to the cell wall due to its hydrophilic nature.

The driving force is the hydrostatic pressure, and the direction of movement is down the water potential gradient.

Plasmodesmata allow for the movement of water from one cell to another through diffusion, allowing for the transfer of water molecules between adjacent cells.

<p>The process is transpiration, and the result is a decrease in water potential in the mesophyll cells, leading to more water entering from the xylem vessels.</p> Signup and view all the answers

<p>The transpiration pull is the negative pressure created at the top of the xylem vessels, which pulls water up the plant, and it contributes to the mass flow of water through the xylem vessels.</p> Signup and view all the answers
