There are commonly four distinct whorls of flower parts: (1) an outer calyx consisting of sepals; within it lies (2) the corolla, consisting of petals; (3) the androecium, or group of stamens; and in the centre is (4) the gynoecium, consisting of the pistils.

What are the functions of the four whorls of a flower?

Each of these whorls contains one of the flower organs, the sepals, petals, stamens, or pistils, respectively. Sepals and petals are not directly involved in reproduction, while the stamens and pistils are the male and female reproductive organs.

  • The calyx: zero or more whorls of sepals at the base.
  • The corolla: zero or more whorls of petals above the calyx.
  • The androecium: zero or more whorls of stamens, each comprising a filament and an anther.
  • The gynoecium: zero or more whorls of carpels, each consisting of an ovary, a style, and a stigma.

What is the function of flower?

The primary purpose of the flower is reproduction. Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

What is the function of petals?

Petals (collectively called the corolla) are also sterile floral parts that usually function as visually conspicuous elements serving to attract specific pollinators to the flower. The calyx and the corolla together are referred to as the perianth.

Which is the sequence of four whorls of flower from outside to inside?

What are whorls in fingerprints?

Whorls – form circular or spiral patterns, like tiny whirlpools. There are four groups of whorls: plain (concentric circles), central pocket loop (a loop with a whorl at the end), double loop (two loops that create an S-like pattern) and accidental loop (irregular shaped).

What is a tree whorl?

A whorl is the circular growth of branches at the same height around the trunk. On most trees, the lowest tree branches are systematically dropped as the tree grows and the sun no longer hits the base of the tree so it is important to include the bottom-most stubs and/or knots where it is evident branches once existed.
