Why?
* Explain the process of absorption of water by roots.
​

Answer 1

Explanation:

Explanation: Water column in xylem vessels are constantly maintained due to cohesion and transportation pull theory. As the xylem vessels are connected to each other, it allows water to stay in a continuous column to the mesophyll cells from the root hairs. Lignin and cellulose of xylem have strongly adhered water.

Answer 2

Answer:

The absorption of water in plants takes place through roots. Water is drawn up by the root hair cells through the process of osmosis. The absorbed water is passed to different parts of the plant through the roots and used to carry out distinct functions.
