Question

explain with example:- 1)Deciduous calyx 2) persistent calyx​

Answer 1

Deciduous calyx

In many flowers the calyx is, deciduous, i.e., it falls off along with the petals just after fertilization as in mustard, etc. In brinjal, Datura, Ocimum, Trapa , etc., the calyx is persistent and remains attached to the ripe fruit. In inferior fruits like guava, the calyx often persists on the fruit.

Persistent calyx (one remaining after the corolla has withered) is a character of Solanaceae as the calyx stays with the matured fruit at the later stage.
