Question

what is the meaning of` essential whorls'.​

Answer 1

Answer:

Essential whorls are also called as reproductive whorls which include stamens and pistil.

Answer 2

Answer:

Sepals are usually green inconspicuous bodies. They protect the essential whorls against mechanical injuries and desiccation in the bud stage. So, their function is mainly protective. Sepals of some plants become coloured like the petals and are called petaloid, e.g. Caesalpinea (B. Krishnachura).
