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): In plants like Citrus and Bougainvillea , hard and pointed structures protect the plant from browsing animals. Reason (R): The protective structures in these plants are formed by the modification of leaflets into sharp spines. In the light of the above statements, choose the correct answer from the
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- C(A) is true but (R) is false
- D(A) is false but (R) is true
Correct answer
C. (A) is true but (R) is false
Step-by-step solution
Assertion (A) is true because thorns are hard, woody, straight and pointed structures found in plants like Citrus and Bougainvillea , which protect them from browsing animals. Reason (R) is false because these protective structures (thorns) are formed by the modification of axillary buds of the stem, not by the modification of leaflets into spines. Spines are modified leaves, which are found in plants like cacti. Answer: (A) is true but (R) is false
