Question

In a floral formula, (K) denotes
A.Polysepalous
B.Gamosepalous
C.Polypetalous
D.Gamopetalous

Answer 1

Hint: The numeric and symbolic representation of different parts of the flower is called a floral formula. It gives us information about the type and number of organs, level of the corolla, symmetry type, and level of ovary, interrelationships, and presence of fusions of different floral parts which are Acalyx, corolla, gynoecium, and androecium.

Complete answer:Gamosepalous- They are called gamosepalous when the sepals of a flower are fused. Eg: Hibiscus and periwinkle are gamosepalous flowers.
Polysepalous- They're called polysepalous when the sepals of a flower are free. Eg: Southern Magnolia and Rose.
Polypetalous-polypetalous defines a flower in which different petals are made of the corolla.
Gamopetalous- The corolla takes the shape of a tube, trumpet, channel, or similarly near-rigid structure, having petals wholly or partially fused.
Hence the correct option is B, Gamosepalous.

Additional information:
At the start of the 19th century, floral formulas were created. Cassel and Martius were the first writers who used them. In his textbook, Grisebach used them to define the characteristics of floral families, to show the numbers of various organs divided by commas, and to highlight fusion. Together with floral diagrams, Sachs used them; he noted their value of being made up of "ordinary typeface." While floral diagrams were commonly used by Eichler in his Blüthendiagramme, he sparingly used floral formulas, mainly for families with simple flowers. In order to explain the ontogenesis of 50 plant species, Sattler's Organogenesis of Flowers uses floral formulas and diagrams. More recent books containing formulas include Judd Prenner’s Plant Systematics. In order to extend the descriptive potential of the formula, it established an extension of the current model and argued that formulas should be used in formal taxonomic descriptions. In his book Floral Diagrams, Ronse De Craene partly used their way of writing the formulas.

Note: Using numbers, letters, and different symbols, a floral formula is a way to describe a flower's structure, providing morphological details about the flower in a short form. Gamosepalous (the number of sepals in the calyx) is symbolized by the letter 'K' in a floral formula. By circling the sepal number, the degree of fusion of the sepals can be indicated.
