Question

In plants, water is transported through
A) Xylem
B) Phloem
C) Stomata
D) Root Hair

Answer 1

Hint: Water is absorbed through the roots and is transported to all the parts of the plant. Transportation in plants is done by Vascular Tissues. Since, for transportation, transporting tissues should be present everywhere in the plants. These vascular tissues transport water and minerals and also prepare food for all the parts of the plant.

Complete answer:
To solve this question, we must know about vascular tissues and their role in the transportation of water.
 We know that vascular tissues are complex permanent tissues that are made up of more than one type of cells.

They are of two types-
1. Xylem is made up of Vessels, Tracheid, Xylem Fibre and Xylem Parenchyma. Out of which except Parenchyma all are dead tissues and Xylem Parenchyma is Living Tissue. The xylem is responsible for the transport of water to all the parts of the plants.
2. Phloem is also made of 4 tissues i.e., Companion cells, Sieve tubes, Phloem Parenchyma and Phloem Fibres. Out of which all are Living accepts Fibres which are dead tissue. Phloem is responsible for transporting the prepared food to various parts of the plant.

Stomata- These are the minute pores present in the leaves through which transpiration and exchange of gases take place.
Root hairs- These are the fine hairs present in the roots through which water and nutrients are absorbed from the soil. These are further connected to the xylem vessels which transports the absorbed water to various parts of the plant.

Thus the correct answer is option ‘A’.

Note: The movement of water in plants is unidirectional i.e., only Upwards because water is taken from the roots and is delivered to all parts of the plant. Transpiration of water through stomata creates an upward pull called the transpirational pull which helps in ascent of sap.
