Question

Why is water potential important for the movement of water in plants?

Answer 1

Hey.

Water potentialis the measurable tendency for water to move from one part of the plant system to another depending on the balance of forces around it. Water potential allows us to predict which way water will move and how fast it will move.  Water potential is expressed in negative numbers.  The highest water potential we find in plants is zero, and water will always moves into areas of more negative water potential.  The most negative areas of a plant are at the top where evaporation is occurring, and the least negative are in the roots.  So on a sunny day, the flow of water is upward from roots toward the leaves.

Thanks.

Answer 2

Importance of water potential

Explanation:

• All life on Earth needs water to survive. Water is that the natural solvent of Earth's biology, mix with our organic chemistry to deliver nutrients, chemical signals, and maintain correct temperature and equilibrium.
• It is vital for the movement of water in plants as a result of it causes water to flow into the roots, since the water potential within the soil is larger than that within the roots.
• additionally, it's what drives transpiration and diffusion and keeps plant cells turgid, and so the plant stiff and upright.
