Question

Which of the following pairs are correctly matched?
A) Assimilatory root – Photosynthesis
B) Fasciculated root – Food storage
C) Stilt root – Mechanical support
D) All of the above

Answer 1

Hint:Roots are the part of a plant. Roots of a plant found underground. They help the plants to absorb the water and minerals from the soil.

Complete answer:
>Assimilatory root: Assimilatory roots are the green, aerial and adventitious roots.These roots prepare their food with the help of a process called as photosynthesis ( a process by which plants make their own food with the help of Sunlight, Water, carbon dioxide and chlorophyll ).That’s why these roots are also called as the photosynthetic roots.These roots absorb moisture from the atmosphere and manufacture food material by the process called photosynthesis.Example – Trapa, Tinospora, etc.
>Fasciculated root: Fasciculated roots are the type of modified adventitious roots.They are the tuberous roots.These roots store food and become thick due to the storage of food.They occur in clusters at the base of the stem.Example – Aspargus, Dahlia, etc.
>Stlit root: Stilt roots are the aerial, adventitious obliquely growing roots.These roots develop from the lower nodes of the stem.These roots give the additional mechanical support to the plant.These roots bear several large overlapping root caps that’s why they are called as multiple root caps.Example – Sugarcane, Maize, etc.These roots also help in the absorption of water and minerals from the soil.
Therefore, it has been clear from the above discussion that all of the given pairs are correctly matched.

Hence, option D is the correct answer

Note:The root is the descending portion of the plant. It is non green and brown in colour. The roots of a plant are not differentiated into nodes and internodes like the stem of a plant. The root tip is protected by the root cap. The root bears small unicellular root hairs that actually absorb the water and minerals from the soil.
