Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Non-essential parts of the flowers are the accessory parts that are not directly involved with the gametes formation and sexual reproduction. The whorls of the calyx (individual unit - sepals) and corolla (individual unit - petals) are involved in the protection of flower and attraction of the pollinators, respectively. So, these are considered to be non-essential parts of flowers.

Hence, the correct answer is 'Sepals and Petals'
