Describe the arrangement of floral members in relation to their insertion on thalamus
Explanation Flowers are highly modified shoot and they consist of corolla, calyx, anther, filament, ovary and thalamus. The petals ( corolla) are arranged in different pattern on the thalamus. There are three different arrangements- Hypogyny: In this arrangement, the petals are arranged below the gynoecium. Thus ,the ovary is superior and rest of the parts are referred to as inferior. Example- China rose Perigyny: In this arrangement, the ovary is partly inferior. The gynoecium is present at the centre and the thalamus is flattened. Example- Strawberry. Epigyny: In this type of arrangement, the ovary is fused with the thalamus and the thalamus rises upwards like a flask. All the other parts, sepals, petals and stamens are present above the ovary. Final Answer Flower is a modified shoot and consists of sepals, petals (corolla), stamen, ovary and thalamus. The petals are arranged in different patterns on the thalamus. There are three different arrangements: Hypogny Perigny Epigny
