Question

The members of the first outermost whorl of flower are called as
A. Sepals
B. Petals
C. Stamens
D. Carpels

Answer 1

Hint: They present a seemingly infinite variety of variations in the range of color, scale, shape, and anatomical arrangement of flowers. From minute blossoms to giant blooms, they vary in size. All flowers have a uniform feature, regardless of their variety, which is the reproduction of the species by seed development.

Complete answer:
Fundamentally, each flower consists of a floral axis on which the vital reproductive organs (stamens and pistils) and generally accessory organs (sepals and petals) are born; the latter can give out to both attract and protect the essential organs from pollinating insects.
A greatly modified stem is the floral axis; unlike vegetative stems, which carry leaves, it is typically contracted such that the parts of the flower on the stem top, the receptacle, are crowded together. The parts of the flower are typically arranged in whorls.

Flowers consist of sets of leaves arranged in whorls that are highly modified. The calyx is considered the outermost whorl of a flower and is composed of sepals. The corolla, which consists of petals, is within the calyx. Sometimes, the sepals are smaller than the petals and less colourful. The androecium, or group of stamens, is subsequently present and the gynoecium, consisting of the pistils, is present in the middle.
So, the correct answer is “Option A”.

Note: Together, the sepals and petals form the perianth, or floral envelope. Typically the sepals are greenish and sometimes resemble reduced leaves, while usually the petals are vibrant and glitzy. Sepals and petals, as in lilies and tulips, that are differentiated are sometimes referred to as tepals. The stamens consist of the androecium, or male sections of the flower, each of which consists of a supporting filament and anther in which pollen is produced.
