Question

The typical floral formula of disc florets is

• A. $K_{pappus}{C}_5{A}_0{\underset{–}{G}}_{\left(2\right)}$
• B. $K_{pappus}{C}_{\left(5\right)}{A}_{\left(5\right)}{\overline{G}}_{\left(2\right)}$
• C. $K_5{C}_5{A}_{\left(9\right)+1}{\underset{–}{G}}_{\left(2\right)}$
• D. $K_0{C}_5{A}_5{\underset{–}{G}}_{\left(2\right)}$

Answer 1

The correct option is B $K_{pappus}{C}_{\left(5\right)}{A}_{\left(5\right)}{\overline{G}}_{\left(2\right)}$

K - for calyx, C - for corolla, A - for androecium, G - for gynoecium.

Disc florets is one of the type of flower in family Asteraceae.

In this, calyx is modified to pappus, i.e., K${}_{pappus}$, petals are 5, i.e., C(5), 5 stamens, i.e., A(5), carpels are 2 with inferior ovary, i.e., G(2).

Therefore, option B is correct.
