In HYPOGYNOUS flowers (e.g. mustard, china rose, brinjal):
AOvary is half-inferior
BThe gynoecium occupies the HIGHEST position on the thalamus; other parts (calyx, corolla, androecium) are situated BELOW it. The ovary is SUPERIOR
CThe ovary is INFERIOR; other parts arise above it
DThalamus margin grows up enclosing ovary
Answer & Solution
Correct answer: B. The gynoecium occupies the HIGHEST position on the thalamus; other parts (calyx, corolla, androecium) are situated BELOW it. The ovary is SUPERIOR
Three thalamus positions: HYPOGYNOUS (gynoecium highest, ovary SUPERIOR — mustard, china rose); PERIGYNOUS (gynoecium central, others at same rim, ovary HALF-INFERIOR — plum, rose, peach); EPIGYNOUS (thalamus grows up enclosing ovary, ovary INFERIOR — guava, cucumber, sunflower ray florets).
