NEETBotanyMorphology of Flowering Plants
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Root hairs are produced specifically in the region of maturation of the root. Reason (R): Cells of the elongation zone gradually differentiate and mature to form the region of maturation, where some epidermal cells develop into root hairs. In the light of the above statements, choose the most appro
Options
- ABoth Assertion and Reason are true but Reason is not the correct explanation of Assertion.
- BBoth Assertion and Reason are true and Reason is the correct explanation of Assertion.
- CAssertion is true but Reason is false.
- DAssertion is false but Reason is true.
Correct answer
B. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Step-by-step solution
According to NCERT, the root is divided into different regions from the apex to the base. The cells of the elongation zone gradually differentiate and mature to form the region of maturation. It is because of this differentiation and maturation process that specialized structures like root hairs arise from some of the epidermal cells in this specific zone. Therefore, both the Assertion and the Reason are true statements, and the Reason correctly explains why root hairs are found in the maturation zone rather than i
