Why (C) is correct: Monocarpic plants are those that flower and produce fruits only once in their lifetime and then die. From the given list, the monocarpic plants are: Wheat, Rice, Marigold, Carrot, and Henbane. These are either annuals (like wheat, rice, marigold) or biennials (like carrot, henbane) that complete their life cycle after a single reproductive event. Thus, there are five monocarpic plants.
Why other options are wrong:
- (A) Two: Incorrect, as there are five monocarpic plants.
- (B) Four: Incorrect, as there are five monocarpic plants.
- (D) Three: Incorrect, as there are five monocarpic plants.
Common Mistake: Students often confuse monocarpic with annuals, but biennials can also be monocarpic. Perennials are typically polycarpic.
NEET Tip: Remember that most annuals and biennials are monocarpic. Perennials like Mango and Orange are polycarpic, meaning they flower and fruit multiple times over many years.
Correct Answer: (C)
