NEETBotanyMorphology of Flowering Plants
A plant has flowers with a bicarpellary, syncarpous, superior ovary that is bilocular with a swollen placenta. Which of the following correctly represents the floral formula symbol for this gynoecium and its corresponding placentation type?
Options
- AG ₂ and Axile
- BG _ (2) and Parietal
- CG _ (2) and Axile
- DG _ (3) and Axile
Correct answer
C. G _ (2) and Axile
Step-by-step solution
The given description of a bicarpellary, syncarpous, superior ovary that is bilocular with a swollen placenta is characteristic of the family Solanaceae. In a floral formula, a superior ovary is denoted by a line below G ( G ), bicarpellary by the number 2, and syncarpous (fused carpels) by enclosing the number in brackets. Thus, the gynoecium is represented as G _ (2) . The placentation in the family Solanaceae is axile, where the ovules are attached to a multilocular ovary's central axis. Answer: G _ (2) and Axil
