Question

The xylems in the plants are responsible for
A) Transport of water
B) Transport of food
C) Transport of amino acids
D) Transport of oxygen

Answer 1

Hint: Xylem sap predominantly consists of inorganic ions and liquids, although it may also comprise a variety of organic chemicals. Transportation is inactive, not motivated by the energy that the tracheal elements themselves expend, which is dead by adulthood and no longer has living material.

Complete Answer:
In vascular plants, xylem is one of two kinds of transport tissue, with phloem being another. The long tracheal elements which transport water are the most recognizable xylem cells. Tracheid and vessel components are characterised by their shape; vessel components are shorter and joined into long tubes known as vessels.

Now, let us find the solution from the options-
- Xylem is a transporting tissue which carries minerals and water to the stem and leaves from the roots.
-It consists of four distinct types of components, namely tracheids, tubes, fibres of xylem, and parenchyma of xylem.
-Phloem transfers food products to other parts of the plant, typically from the leaves.

Thus, the correct answer is option (A) Transport of water.

Note: Primary xylem is derived from procambium during primary development. Protoxylem and metaxylem are included. Following the protoxylem, Metaxylem grows but before secondary xylem. Metaxylem is larger than protoxylem of vessels and tracheids.
