Question

Glumes represent
A. Bracts
B. Sepals
C. Petals
D. Stamens

Answer 1

Floral formula is a way of representing a flower's structure with numbers, letters, and different symbols, providing important details about the flower in a compact form. It can be used to describe specific organisms or it can be used to classify higher taxa, typically with organ number ranges. Floral formula is a numerical, letter, and symbol representation of flower structure. K stands for sepals, A stands for stamens, G stands for carpels, B stands for bracts, Bt stands for bracteoles, and C stands for petals.

Complete explanation:
Option A: Bracts are represented by glumes. In the flowers of grasses (Poaceae) and sedges, glumes are a basal, membranous, outer sterile husk or bract (Cyperaceae). A bract is a modified or specialised leaf, most often connected with a reproductive structure like a flower, inflorescence axis, or cone scale. Bracts are also distinct from the leaves of the foliage. They may be smaller, bigger, or have a different colour, texture, or form. They usually have a different appearance than other parts of the flower, such as the petals or sepals.
So, the option A is correct.
Option B: A sepal is a part of an angiosperm's flower. Sepals are usually green and serve as cover for the flower in bud as well as support for the petals when in bloom.
So, option B is incorrect.
Option C: Petals are modified leaves that cover a flower's reproductive organs. To attract pollinators, they are often brightly coloured or oddly shaped. The corolla refers to a flower's whole collection of petals. Petals are normally followed by a group of modified leaves known as sepals, which form the calyx and lie just beneath the corolla.
So, option C is incorrect.
Option D: A stamen is the pollen-producing male reproductive organ of flowering plants. An anther is bound to a filament by a filament in the stamen. Microsporangia, which will eventually turn into pollen grains, are found inside the anther.
So, option D is incorrect

Hence, Option A is the correct answer.

Note:
A bract is a modified or specialised leaf, most often connected with a reproductive structure like a flower, inflorescence axis, or cone scale. Bracts are sometimes (but not always) distinct from the leaves of the foliage. They may be smaller, bigger, or have a different colour, texture, or form. They usually have a different appearance than other parts of the flower, such as the petals or sepals. Each floret in grasses is surrounded by a pair of papery bracts called the lemma (lower bract) and palea (upper bract), and each spikelet (group of florets) has a further pair of bracts called glumes at its base.
