Answer 1

$\huge{\underline{\mathtt{\red{❥A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

• Conduction of water through the xylem, from roots to upper parts of plants, is due to many forces acting together.

• One of the forces responsible for this is root pressure.

• Root pressure is osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.

• Root pressure helps in the initial transport of water up the roots.

Answer 2

Answer:

please mark as brilliant answer

Explanation:

'Root Pressure'. It is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day.
