Question

Q.1 How is transpiration pull responsible for upward movement of water?​

Answer 1

Answer:

Here's your Answer.

Explanation:

During transpiration process, water molecules get evaporated from the stomata. In this process, the concentration of water is reduced in mesophyll cells, which results in lowering the cells sap of mesophyll compared to that of the xylem vessels. This results in upward pull of water from the root to the mesophyll cells by generating a negative pressure in xylem vessels to pull the water from the soil.

Hope it helps you.

Good Luck.

Answer 2

Answer:

During transpiration process, water molecules get evaporated from the stomata. ... This results in upward pull of water from the root to the mesophyll cells by generating a negative pressure in xylem vessels to pull the water from the soil.

Explanation:

Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecule

Overall, water is transported in the plant through the combined efforts of individual cells and the conductive tissues of the vascular system. ... It is carried upward through the xylem by transpiration, and then passed into the leaves along another water potential gradient.
