Question

In papilionaceous "Keel" is :-

• A. Posterior petal
• B. Lateral petal
• C. Anterior petal
• D. Both (1) & (3)

Answer 1

The correct option is A Posterior petal

The keel is the petals that are situated lower than the wings and are enclosed by them. They have concave sides and correspond with the shape of the wings. They are fused at their bases or stuck together to form a boat-shaped structure that encloses the essential flower organs, the androecium, and gynoecium. So, the correct option is 'posterior petal'.
