Family Fabaceae differs from Solanaceae and Liliaceae. With respect to stamens, which feature is specific to Fabaceae only?
How many plants among the following have stamens with different lengths?
The term 'polyadelphous' is related to:
Answer & NCERT explanation
Correct answer: C — A-IV, B-II, C-I, D-III
Monoadelphous (all stamens fused) - China rose (Hibiscus), Diadelphous (9+1 fusion) - Pea (Pisum), Polyadelphous (multiple bundles) - Citrus, Epiphyllous (attached to perianth) - Lily. This matches NCERT examples of different stamen fusion patterns in various plant families.

Stamens of flower may be united with other members such as petals or among themselves. When stamens are attached to the petals, they are epipetalous as in brinjal, or epiphyllous when attached to the perianth as in the flowers of lily. The stamens in a flower may either remain free (polyandrous) or may be united in varying degrees. The stamens may be united into one bunch or one bundle (monadelphous) as in china rose, or two bundles (diadelphous) as in pea, or into more than two bundles (polyadelphous) as in citrus. There may be a variation in the length of filaments within a flower, as in Salvia and mustard.
NTA tests your knowledge of how stamens unite with other floral parts and with each other. Students confuse monadelphous (one bundle, like china rose) with diadelphous (two bundles, like pea) and polyadelphous (multiple bundles, like citrus). Remember: the prefix tells the bundle count — 'mono' = 1, 'di' = 2, 'poly' = many. When stamens attach to petals, they're epipetalous; when attached to the perianth, they're epiphyllous. This concept appears frequently because it requires precise botanical terminology and example matching, which is typical NEET content for flowering plant morphology.
