Question

Which of the following information is not available in floral diagram?

• A. Aestivation of calyx
• B. Aestivation of corolla
• C. Placentation of ovary
• D. Position of ovary on thalamus

Answer 1

The correct option is D Position of ovary on thalamus

A floral diagram provides information about the number of parts of the flower, their arrangement and the relation they have with one another. The position of the mother axis w.r.t., the flower is represented by a dot on the top of a floral diagram. Calyx, corolla, androecium and gynoecium are drawn in successive whorls, calyx being the outermost and gynoecium being in the centre. It provides with the placentation of ovary even. While the position of the ovary on thalamus is never provided by a floral diagram.

So, the correct answer is 'Option D- Position of the ovary on thalamus'.
