Assertion (A) Explained
Monocotyledonous plants, commonly known as monocots, exhibit a unique root system.
- The primary root in these plants is indeed short-lived.
- It is typically replaced by a fibrous root system that consists of numerous roots emerging from the base of the stem.
This characteristic is a fundamental aspect of monocot structure.
Reason (R) Explained
The fibrous root system is crucial for the survival and growth of monocots.
- This type of root system allows monocots to develop a vast network of roots.
- Such an extensive system enhances their ability to absorb water and nutrients effectively.
The fibrous roots spread out horizontally and are closer to the soil surface, making them efficient in capturing moisture and nutrients from the top layers of soil.
Relationship between A and R
- Both the assertion and reason are true statements.
- The reason (R) serves as an explanation for the assertion (A) since the fibrous root system is a direct consequence of the short-lived primary root in monocots.
In summary, the primary root of monocots is transient, and the subsequent development of a fibrous root system supports their adaptation and efficiency in resource acquisition. Thus, the correct answer is option 'A': Both A and R are true, and R is the correct explanation of A.

The assertion is true as in monocotyledonous plants, the primary root is indeed short-lived and is replaced by a fibrous root system originating from the base of the stem. The reason is also true and correctly explains the assertion because the fibrous root system provides a more extensive network for efficient water and nutrient absorption from the soil.
Line in NCERT: "In monocotyledonous plants, the primary root is short lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system."
