NEETBotanyMorphology of Flowering Plants
Observe the given floral formula: , Bisexual, K _ 2+2 C ₄ A _ 2+4 G _ (2) Identify the family it represents, its characteristic placentation, and a special feature of its ovary.
Options
- ABrassicaceae ; Axile placentation ; Basal ovules
- BSolanaceae ; Axile placentation ; Swollen placenta
- CFabaceae ; Marginal placentation ; Monocarpellary ovary
- DBrassicaceae ; Parietal placentation ; False septum
Correct answer
D. Brassicaceae ; Parietal placentation ; False septum
Step-by-step solution
The given floral formula is , Bisexual, K _ 2+2 C ₄ A _ 2+4 G _ (2) . The presence of 4 petals ( C ₄ ) and tetradynamous stamens ( A _ 2+4 ) are characteristic features of the family Brassicaceae (mustard family). Members of Brassicaceae exhibit parietal placentation, where the ovules develop on the inner wall of the ovary. The ovary is initially one-chambered, but it becomes two-chambered due to the formation of a false septum (replum). Thus, the correct combination is Brassicaceae, Parietal placentation, and Fals
