Question

The floral diagram does not give information about the

• A. number of sepals
• B. position of ovary
• C. placentation
• D. number of carpels

Answer 1

The correct option is B position of ovary

The floral diagram gives information about
1. position of mother axis with respect to flower
2. The number of sepals, petals, whether they are fused or free and the aestivation(arrangement of sepals and petals with respect to one another)
3. The number of stamens, free or fused and their attachment to other floral parts
4. The number of carpels, free or fused and the placentation (arrangement of ovules in the ovary).

But the floral diagram does not give information about the position of the ovary, whether it is superior or inferior or half inferior.
If the position of ovary is above all other floral parts, it is called a superior ovary and the flower is said to be hypogynous.
If the position of ovary is below other floral parts, it is called an inferior ovary and the flower is said to be epigynous.
If the ovary is almost at the same level as other floral parts, then the ovary is said to be half inferior and the flower is called perigynous.
