NEETBotanyAnatomy of Flowering Plants
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In dicotyledonous plants, lateral roots are endogenous in origin. Reason (R): Lateral roots originate from the pericycle, which is located deep within the root inner to the endodermis. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- B(A) is correct but (R) is not correct
- CBoth (A) and (R) are correct and (R) is the correct explanation of (A)
- D(A) is not correct but (R) is correct
Correct answer
C. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
In dicotyledonous roots, the lateral roots arise from the pericycle. Because the pericycle is a deep-seated layer located inner to the endodermis, the origin of lateral roots is termed endogenous. Thus, both the Assertion and the Reason are correct, and the Reason correctly explains the Assertion. Answer: Both (A) and (R) are correct and (R) is the correct explanation of (A)
