Question

Why are petals and sepals called non essential whrols of flowers

Answer 1

because these two do not form a fruit

Answer 2

Answer:

Consequently, the calyx (sepals) and the corolla (petals) are sterile and are referred to as the non-essential or accessory parts of the flower because they do not directly participate in the process of sexual reproduction. At most, these flower parts only participate indirectly by attracting pollinators.
