Feb 21, 2022 · Receptacle. The receptacle is the thickened top portion of the pedicel that connects to the flower’s base. This part supports the flower and holds the floral whorls. The receptacle becomes part of the fruit in certain fruits such as raspberries and strawberries.

Aug 26, 2024 · Whorls of Flowers. In the anatomy of flowers, the arrangement and function of floral parts are organized into distinct whorls. Each whorl plays a crucial role in the flower’s reproductive process and overall structure. The primary whorls of a flower include the calyx, corolla, androecium, and gynoecium.

Flowers have two primary parts: the vegetative part, which includes the petals and the sepals, and the reproductive part, encompassing the stamen (male reproductive organ) and the pistil or carpal (female reproductive organ).
The primary function of a flower is reproduction, ensuring the survival of the species. Through the process of pollination and fertilization, flowers produce seeds. Each seed contains a new plant, waiting for the right conditions to grow.
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. This process can occur through self-pollination or cross-pollination: 1. Self-pollination: This occurs when the pollen from an anther deposits onto the stigma of the same flower or another flower on the same plant. Self-pollination is common ...

These components are arranged in whorls and attach to an area called the receptacle, which is at the end of the stem that leads to the flower. This stem is called the peduncle.
Understand the structure of a flower, and how to interpret and construct basic floral diagrams. Identify the number and features of each whorl in fuschia and geranium flowers, and construct the correct floral formulae.
The flower stalk forms a receptacle or torus at its distal end. The parts of a flower are arranged in whorls on the torus. The four main parts or whorls (starting from the base of the flower or lowest node and working upwards) are as follows: Calyx: the outer whorl of sepals; typically these are green, but are petal-like in some species.
Floral whorls: (a) Calyx: It is the first or outermost protective whorl. Individual member of calyx is called a sepal which is generally green. (b) Corolla: It is the second or attractive whorl present inner to calyx. Each member of corolla is called a petal. ADVERTISEMENTS: (c) Androecium: It is the third or male whorl.
