Name a cultivated plant in which neither fruits nor seeds are formed.
Concept: This question tests your knowledge of plant reproduction, specifically focusing on plants that reproduce vegetatively rather than through seeds or fruits.
Why (A) is correct: Banana is a classic example of a cultivated plant that is typically parthenocarpic, meaning it produces fruits without fertilization. The fruits are seedless, and the plant is propagated vegetatively using suckers or rhizomes. Wild bananas do have seeds, but the cultivated varieties are sterile triploids.
Why other options are wrong:
- (B) Orange produces fruits with seeds, though some varieties can be seedless due to parthenocarpy.
- (C) Pomegranate produces fruits with numerous seeds.
- (D) Guava produces fruits with many seeds.
Common Mistake: Students might confuse naturally seedless fruits (parthenocarpy) with fruits that have very small or inconspicuous seeds.
NEET Tip / Mnemonic: Remember that many commercially important fruits are seedless due to parthenocarpy, which is often induced or naturally occurring in cultivated varieties. Think of 'B' for Banana and 'B' for 'Big' seedless fruit.
Correct Answer: (A)
