Correct answer
C. % , Bisexual, K _ (5) C _ 1+2+(2) A _ (9)+1 G ₁
Step-by-step solution
Pisum sativum (garden pea) belongs to the family Fabaceae. The flowers of Fabaceae are zygomorphic ( % ) and bisexual. The calyx consists of 5 united sepals ( K _ (5) ). The corolla is papilionaceous, consisting of 5 petals: 1 standard, 2 wings, and 2 fused keel petals ( C _ 1+2+(2) ). The androecium consists of 10 stamens which are diadelphous ( A _ (9)+1 ). The gynoecium is monocarpellary with a superior ovary ( G ₁ ). Therefore, the correct floral formula is % , Bisexual, K _ (5) C _ 1+2+(2) A _ (9)+1 G ₁ . Answ
