Question

function of xylem and guard cell​

Answer 1

Explanation:

Grard cells: Surrounding each stomata are two guard cells, which regulate the opening and closing of stomata to facilitate gas exchange and control transpiration in plants.

Xylem: Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.

Answer 2

Answer:

Xylem: the structural function

lignin plays several other important biological roles in plants because it is much less hydrophilic then Cellulose and Hemi cellulose, it prevent the absorption of water by these

Guard cell: guard cell are the cell surrounding each stoma. they help to regulate the rate of transpiration by opening and closing the stomata.
