Answer 1

The correct option is D Tepal

A. Perianth can be defined as the non-reproductive part of the flower which consists of calyx and corolla and surrounds the sexual reproductive organ.

B. Sepals (calyx) are a modified form of leaves which form the outer whorl of a flower and protects the flower.

C. Petal (corolla) are also modified leaves which are often brightly coloured or with unusual shapes to attract pollinators.

D. Tepal is a term used when the sepals (calyx) and the petals (corolla) cannot be differentiated or classified easily.

So, the correct answer is 'Tepal'.
