Answer 1

Hint: The flowers of different species show different characteristics. The fusion of sepals and petals is known as perianth and mostly belongs to monocots.

Complete answer:
When calyx and corolla are not differentiated and are fused, it is known as tepals. Tepal is seen in the family Liliaceae and belongs to the class Monocotyledonae. There are 6 colored tepals present. In the family Poaceae, the perianth is reduced and represented by lodicules. All the flowers that belong to these two families show no such differentiation in the flower appendage linkage.

Additional Information: Some characteristics of class Poaceae
