Essential Whorls
Petals and Sepals make up a flower's vegetative portion.
The stamen, also known as the androecium, is the male reproductive organ found in the reproductive portions of a flower. Anthers and filaments make up both of its components.
Gynoecium, another name for the female reproductive system's pistil.
- Because they encapsulate the flower's sexual components and give rise to the stamen (the male reproductive organ) and pistils, the androecium and gynoecium are referred to as the important whorls (female reproductive organ).
- A flower is referred to as bisexual if it has both of the necessary whorls. A flower is referred to as a unisexual flower if it just has stamens or pistils.
- Because they are not directly involved in the development of gametes and seeds or the process of sexual reproduction, the calyx and the corolla are known as the non-essential whorls.
- The outermost accessory group of floral leaves, which consists of sepals, is known as the calyx. Sepals are typically green, unassuming bodies that shield the vital whorls from mechanical damage and desiccation in the bud.
- The corolla is the flower's secondary accessory whorl, and it is made up of petals. Brightly coloured petals add to the blooms' showiness and allure.
Summary:-
The 'essential whorls' of a Flower are (a) Calyx (b) Corolla (c) Androcium (d) Gynoecium
Androcium and Gynoecium are the 'essential whorls' of a flower. The reproductive organ of a plant is its flower
