Question: 99: The Floral Diagram represents which one of the following families?
(1) Fabaceae
(2) Brassicaceae
(3) Solanaceae
(4) Liliaceae
Answer: Option (2)
Explanation:
The floral diagram shown corresponds to the characteristic features of the Brassicaceae family.
Flowers of Brassicaceae are actinomorphic, bisexual, and tetramerous, meaning floral parts are arranged in multiples of four.
The calyx consists of four sepals arranged in two whorls of two each, and the corolla consists of four free petals arranged in a cruciform manner.
The androecium shows a tetradynamous condition, with six stamens where four are long and two are short.
The gynoecium is bicarpellary, syncarpous, with a superior ovary and parietal placentation.
These diagnostic features are represented in the floral diagram of Brassicaceae.
Therefore, the correct answer is Brassicaceae.
