Question

Roots that store food material is called
A. Taproot
B. Primary root
C. Fibrous root
D. Tuberous root

Answer 1

Hint: The roots in vascular plants are organs that provide anchorage to the plant and help in the uptake of essential substances into the plant body, which helps the plant to grow faster and taller. The roots lie below the surface of the soil, but few of them are aerial, i.e. they grow up above the ground. Roots of carrot is a type of root that stores food material.

Complete answer: Tuberous roots are enlarged fleshy roots that have been modified as a storage organ with shoots being produced at one end and the roots being produced at the other end. Sweet potato is a product of tuberous roots. They botanically differ from true tubers because they are modified stem tissues.
a) Taproot: These are the large, dominant, central roots from which other roots arise laterally. The taproot is straight and is very thick and is tapering in shape and grows downwards directly. In few plants such as carrot, tap root acts like storage organs and it has been cultivated as a vegetable.
b) Primary root: It is an organ that forms at the root pole of the plant embryo. The primary root continues the growth of the embryonic radicle. Sometimes the primary root is called tap root.
c) Fibrous root: This root system is the opposite of the taproot system. They are usually formed by thin, moderately roots that branch from the stem. The fibrous root looks like a thick mat made up of roots when the tree has reached maturity.
Hence, the correct answer is option D.

Note: Roots are underground structures that are present in the plant that has been developed from the radicle. They absorb water, nutrients, and minerals from the soil. They help the plants by anchoring the plant to the ground. A specialized lateral root that functions as a storage organ is called a tuberous root or the storage root. For example, beets and carrots are tuberous roots which are the modification of taproots.
