Question

Floral formula of mustard plant of Brassicaceae family is:

• A. Br \quad Brl \quad \% \quad $\odot$^$\uparrow$ \quad $K_4$ \quad $C_4$ \quad $A_{4+2}$ \quad $G_{(2)}$
• B. Br \quad Brl \quad \% \quad $\odot$^$\uparrow$ \quad $K_{2+2}$ \quad $C_4$ \quad $A_{2+4}$ \quad $G_{(2)}$
• C. Ebr \quad Ebrl \quad $\oplus$ \quad $ $\odot$^\uparrow$ \quad $K_4$ \quad $C_4$ \quad $A_{4+2}$ \quad $G_{(2)}$
• D. \textbf{Ebr} \quad \textbf{Ebrl} \quad \textbf{$\oplus$} \quad \textbf{$\uparrow$} \quad \textbf{$\odot$} \quad \textbf{$K_{2+2}$} \quad \textbf{$C_4$} \quad \textbf{$A_{2+4}$} \quad \textbf{$G_{(2)}$}

Hint:

Floral formulas are used to represent the structure of flowers. Make sure to identify the number of parts for each floral whorl (sepals, petals, stamens, and pistils) to accurately determine the formula.

Answer 1

The Correct Option is D

The floral formula for the mustard plant (a member of the Brassicaceae family) is: \[ \text{Ebr} \, \text{EbrI} \, \% \quad \text{K}2+2 \, \text{C}4 \, \text{A}2+4 \, \text{G}(2) \] - \( K \) refers to the calyx (sepals), and there are 4 of them (hence \( K4 \)).
- \( C \) refers to the corolla (petals), and there are 4 of them (hence \( C4 \)).
- \( A \) refers to the androecium (stamens), with 2+4 stamens in two groups (hence \( A2+4 \)).
- \( G \) refers to the gynoecium (pistil), which is bicarpellary (hence \( G(2) \)).
This is the correct floral formula for the mustard plant, hence option 4 is the correct answer.
