Match structures given in Column I with functions given in Column II.
| Column I | Column II |
| (i) Stomata | (a) Absorption of water |
| (ii) Xylem | (b) Transpiration |
| (iii) Root hairs | (c) Transport of food |
| (iv) Phloem | (d) Transport of water |
| (e) Synthesis of carbohydrates |
Correct Answer:
(i) Stomata - (b) Transpiration
(ii) Xylem - (d) Transport of water
(iii) Root hairs - (a) Absorption of water
(iv) Phloem - (c) Transport of food
Explanation:
Water and dissolved minerals are absorbed by the root hair of a plant by the conducting tissue xylem, through a process known as diffusion.
The differences between the transport of materials in Xylem and Phloem are given below:
| Transport of materials in Xylem | Transport of materials in Phloem |
| i> Xylem tissues helps in the transport of water and minerals. | i> Phloem tissues helps in the transport of food and minerals. |
| ii> Water is transported upwards from roots to aerial parts of the plant. | ii> Food is transported in both upward and downward directions. |
| iii> Transport in xylem requires forces such as transpiration pull. | iii> Transport of food in phloem requires energy in the form of ATP. |
