Question

The xylem in the plants is responsible for
(a)Transport of water
(b)Transport of food
(c)Transport of amino acid
(d)Transport of oxygen

Answer 1

Hint: Xylem and phloem are two vascular tissues used in the transportation of food, water, and nutrients in the plants. Phloem lies exterior to stem carries food from leaves to different parts of the plants. Vascular cambium is present between the vascular tissue responsible for increasing the diameter of stem and root..

Complete answer:
Xylem transports water and nutrients that enter the plant in the root up through the stem and out to all parts of the leaf. Xylem has two types of cells known as tracheids and vessel elements. Tracheids and vessel elements from the tube-shaped structure that provides a pathway for water and minerals from the roots to the leaves. Tracheids are found in all vascular plants but vessels are found only in angiosperms.

Additional Information:
 -Vascular tissues consist of a series of elements that form tubes throughout the plants. It is made up of two different kinds of tissues- xylem and phloem.
-Types of xylem
I- Xylem= tracheids, vessel members and parenchyma
II- Primary Xylem= protoxylem and metaxylem
III- Secondary Xylem
-Tracheids are elongated and lignified cells have tapering end walls that overlap with the adjacent tracheids cell. They give support to the plants.
-Vessel members are cylindrical, tube-like structures formed by the fusion of several cells end to end in a row.

So, the correct answer is ‘transport of water’.

Note: -Phloem runs parallel to the xylem and carries sugar that is produced in the leaves, dissolved in fluid to all parts of the plants.
-Phloem is composed mostly of cell sieve- tube cells and companion cells.
