📚 Practice Concept
📖 NCERT Source

Born in November 1904 in Jaipur (Rajasthan) Panchanan Maheshwari rose to become one of the most distinguished botanists not only of India but of the entire world. He moved to Allahabad for higher education where he obtained his D.Sc. During his college days, he was inspired by Dr W. Dudgeon, an American missionary teacher, to develop interest in Botany and especially morphology. His teacher once expressed that if his student progresses ahead of him, it will give him a great satisfaction. These words encouraged Panchanan to enquire what he could do for his teacher in return.

Which of the following statements regarding different types of fruits are NOT correct? S1: True fruits are exclusively derived from the fertilised ovary, without any other floral parts contributing to their formation. S2: In false fruits like apple and strawberry, the thalamus is the primary edible portion, making them a type of parthenocarpic fruit. S3: Parthenocarpic fruits, such as banana, develop without fertilisation and are characteristically seedless. S4: Fruits developing solely from the ovary are always the result of fertilisation and cannot be parthenocarpic. S5: Mango and guava are examples of true fruits where the entire edible part originates from the matured ovary wall. S6: All fruits that develop without fertilisation are necessarily false fruits because they involve atypical development.
