Welcome to the NCERT Solutions for Class 7 Science - Chapter Transportation in Animals and Plants. This page offers a step-by-step solution to the specific question from Exercise 1, Question 3:
Choose the correct option:
(a) In plants, water is transported through
(i) xylem (ii) phloem
(iii) stomata (iv) root hair
(b) Water absorption through roots can be increased by keeping the plants
(i) in the shade
(ii) in dim light
(iii) under the fan
(iv) covered with a polythene bag

(iv) covered with a polythene bag
(a); (i) Xylem
The water and minerals from soil enters the plant through the roots and then pass into the xylem, then from this the dissolved mineral and water moves in the upward direction that occurs from the soil to the uppermost leaves. This upward movement of minerals and water against the gravitational force through the xylem is known as ascent of sap. Xylem tissue consists of living and non-living cells; and non- living cells consists of tracheary elements: tracheids and vessel elements.
(b); (iii) Under the fan
Water absorption occurs through the roots can be enhanced by keeping the plants under the fan because of the transpiration process is boosted. Higher vapour pressure differences between leaf air spaces and the external air increases the transpiration rate.
