— Concept: This question tests your understanding of fruit morphology, types of fruits, and the process of fruit…Concept: This question tests your understanding of fruit morphology, types of fruits, and the process of fruit formation, particularly parthenocarpy.
Why (B) is correct:
I. True: A fruit is typically defined as a mature or ripened ovary, developed after fertilization. It consists of the pericarp (fruit wall) and the seeds inside. The pericarp develops from the ovary wall, and the seeds develop from the ovules.
II. True: Most fruits are eucarpic (or true fruits), meaning they develop solely from the ovary of a flower. Examples include mango, tomato, and pea.
III. True: Parthenocarpic fruits are indeed formed without the process of fertilization. This means they are typically seedless. Examples include banana, pineapple, and some varieties of grapes.
IV. False: Parthenocarpic fruits are highly valued in the fruit industry because they are seedless. This makes them more desirable for consumption and processing. For example, seedless grapes and bananas are very popular.
Why other options are wrong:
A) Incorrect because statement IV is false, not true.
C) Incorrect because statement III is true, not false.
D) Incorrect because statements I, II, and III are true, not false.
NEET Tip: Remember that 'true fruits' develop only from the ovary, while 'false fruits' (or accessory fruits) involve other floral parts like the thalamus (e.g., apple, strawberry).
