What is floral formula in biology?

Floral formula is a means to represent the structure of a flower using numbers, letters and various symbols, presenting substantial information about the flower in a compact form. It can represent particular species, or can be generalized to characterize higher taxa, usually giving ranges of organ numbers.

Is the floral formula of?

(B) The floral formula for Liliaceae is ⊕P3+3A3+3G−3. (C) In pea flower the stamens are monadelphous. (D) The floral formula for Solanaceae is ⊕K(5)C(3)G(2).

What are two types of inflorescence?

The arrangement of flowers on the floral axis is called an inflorescence. Based on whether the apex gets converted into a flower or it continues to grow, the two types of inflorescences are identified as racemose and cymose.

What is called inflorescence?

Inflorescence, in a flowering plant, a cluster of flowers on a branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate).

Are roses Actinomorphic?

When the different members of each whorl are alike, the flower is regular and is referred to as actinomorphic, or radially symmetrical, as in the petunia, buttercup, and wild rose. Differences in size or shape of the parts of a whorl make the flower irregular (as in the canna and Asiatic dayflower).

Why are petals and sepals considered accessory parts?

The sepals and petals are accessory parts or sterile appendages; though they protect the flower buds and attract pollinators, they aren't directly involved with sexual reproduction.

What are the accessory parts of a flower?

Flower structures can be divided into two groups: the essential organs and the accessory organs. The essential organs are the reproductive structures, which include the stamens (male) and the pistils (female). The accessory organs are the sepals and petals, which surround and protect the essential organs.

What is the female reproductive part of a flower?


What are accessory whorls of a flower?

Accessory whorls are also called as vegetative whorls which include sepals and petals. Essential whorls are also called as reproductive whorls which include stamens and pistil. A flower can be complete or incomplete based on the number of whorls present in it.
