NEET BIOLOGY

Detailed explanation-1: -Water from the roots is ultimately pulled up by this tension. Negative water potential draws water from the soil into the root hairs, then into the root xylem. Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf through the stoma.

Detailed explanation-2: -Plants and trees couldn’t thrive without capillary action. Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it’s way all the way up to the branches and leaves.

Detailed explanation-3: -Water is highly cohesive-it is the highest of the non-metallic liquids. Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible.

Detailed explanation-4: -The attraction to the tree root tissue (cohesion) becomes stronger than the attraction to the other water molecules (adhesion). This sends the water drop up through the roots of the tree in narrow pipes called capillaries or xylem.

Detailed explanation-5: -The cohesive forces present between the water molecules keeps them together and provides stability to them. The adhesive forces help the water molecules to stick to other surfaces like glasses, leaves, or any other plant surfaces. The water molecules stick to these surfaces and thus do not runoff.
