1AnswerA·
Concept: This question tests your knowledge of the different types of androecium arrangements based on the length of stamens, a key characteristic used in plant morphology and classification.
Why (A) is correct: An androecium with six stamens, where four are long and two are short, is specifically termed tetradynamous. This arrangement is characteristic of the Brassicaceae (mustard) family.
Why other options are wrong:
- (B) Didynamous: Refers to an androecium with four stamens, two long and two short.
- (C) Diadelphous: Describes stamens united into two bundles, typically seen in Fabaceae (pea family).
- (D) Diplostemonous: Indicates stamens arranged in two whorls, with the outer whorl alternating with petals and the inner whorl opposite to petals.
NEET Tip: Remember the specific stamen arrangements and their associated plant families, especially tetradynamous (Brassicaceae) and didynamous (Lamiaceae/Scrophulariaceae).
Correct Answer: (A)
Tetradynamous
