Question

What does the following floral formula represent? ${ K }_{ 5 }{ C }_{ 5 }{ A }_{ 5 }{ G }_{ (2) }$

​

Answer 1

Hint: It represents sepals petals and anthers and carpel. When the number of floral parts is numerically represented. It is known as a floral formula. It gives us information about flower symmetry. its presence
Of fusion, level of organs, and the relationship between different floral parts.

Complete step by step answer:
- Flowers are defined by the number of organs, like petals sepals carpels, and stamens
- Floral formula represents the structure of a flower in numeric, letters and symbols forms. That's why floral formulas are considered the simplest way to represent the salient features of a flower.
- Floral formulae represent floral symmetry, position, and insertion of the ovary, the number of parts, connotations, and adnation.

- Floral formula consists of five symbols. These are a number of sepals, numbers of petals, floral symmetry, number of carpels and number of stamens.
- In the following question K represents calyx (sepals), C represents Corolla (petals), A represents androecium (stamens), G represents gynoecium (carpels). It means the flower of the family has 5 free sepals, 5 free petals, 5 anthers, and two carpels that are fused.

Additional information:
- Floral whorls present in concentric circles. Sepals are for the outermost circle, petals are the second one, third is for stamen and the carpel is the innermost.
- For four-lobed structures, stamens are represented as dithecous anthers and for monothecous anthers, it is represented as uniform shape.
- Bracteoles are towards the sides and bract at the base.
- At the top of the floral diagram, the mother axis is represented by a small circle with a dot.
- When there is an organ missing then it is denoted by 0 after its respective symbol.

Note: Always start with a bract and bracteole when beginning to write the floral formula, then moving towards the sexuality or symmetry of the flower and then specify their floral parts.
- The numbers representing each part of the flower must be written after their corresponding symbol.
