Question

In, Asparagus, the roots are-
A. Fasciculate
B. Conical
C. Napiform
D. Nodulated

Answer 1

Hint: Root hairs also called as absorbent hairs are outgrowths of a trichoblast. It is a hair forming cell on the epidermis of a plant root. These structures are only rarely branching lateral expansions of a single cell. They are found in the region of maturation. Also known as the zone of differentiation of the root. As we know that, roots have a primary function to provide water which it obtained from soil and provide water to upper parts of plants. It also takes up nutrients from soil which helps in photosynthesis and other essential activities required for the growth of plants.

Complete answer:
Option A Fasciculate-: Asparagus roots are fasciculated roots because its roots are multiple and starch is stored in the roots as multiple fasciculated bundles. It grows from an underground root system of fleshy storage roots attached to an underground stem called a rhizome.
Option A is correct.
Option B Conical: Conical roots are the type of roots which are conical in shape. Widest at the top and tapering steadily towards the bottom for example in carrots.
Option B is not correct.
Option C Napiform: Napiform roots have a top-like appearance. It is the one much swollen at the base so as to become broader than that in the turnip. The tap root system's alterations are known as napiform. Examples- sugar beet and turnip.
Option C is not correct.
Option D Nodulated: Nodulated roots are bead-like structures on the roots of plants that are symbiotically connected with the nitrogen-fixing bacteria Rhizobium. This helps in gaseous nitrogen from the atmosphere into the nodule which is then used in the plant.
Option D is not correct.

Therefore, Option A is the correct answer.

Note:
The root system is usually extensive and root hairs as we discussed absorb water as its surface helps in more water absorption. Water enters the root cells and then moves from cell to cell until it reaches the root cortex it goes on to xylem vessels to be transported to the leaves. Root hair has a higher concentration of cell sap than the surrounding soil water.
