Question

DESCRIBE the structure of xylem tissue ...

Answer 1

heya !!!

■Xylem have DEAD LONG AND HOLLOW VESEELS .

■Xylem HAVE LIGNIFIED CELL WALL THICKENINGS.

■Movement of water is in upward direction from soil to leaves.

■Xylem transports water and minerals obtained from the soil.

■Xylem tissues of plants have interconnected network of vessels and tracheids of roots , stems and leaves .

■They form continuous system of water conducting channels which reach all parts of a plant .

■At roots , cells in contact with the soil actively take up ions creating a difference in the concentration of these ions between the root and soil ( root pressure ) .

■Thus , water enters into roots from the soil eliminating the difference . Hence , there is a steady movement of water into root xylem from the soil that creates a column of water pushing it upwards .
