Question

In Gramineae, the perianth is represented by small scaly lodicules which are generally
(a) Two
(b) Three
(c) Four
(d) Five

Answer 1

Hint: The flower of Gramineae is characterized by bracteate, bracteolate, sessile, incomplete, bisexual, zygomorphic, hypogynous, homochlamydeous. It consists of two perianth, three stamens, and monocarpellary gynoecium with a single ovule on the basal placentation.

Complete answer:
The largest number of species of flora in India are from the family Poaceae is also known as Gramineae. The members of the Gramineae families mostly include grasses, wheat, rye, etc. The flowers of Poaceae are arranged in an inflorescence called spikelet and these spikelets are composed of spikes or panicles. The spikelet of the grass is composed of two glumes or basal bracts that are sterile. They may result in the formation of a single floret called a simple spikelet or even many florets called compound florets. When floret applied to grasses, it alludes to the flower and two fertile bracts that generally encase the flower, the lemma, and palea. The perianth is diminished to negligible structures, lodicules that may be categorized as the modified sepals, arranged underneath the ovary, and as needs are, the fruit is single-developed with the testa adnate to the pericarp, a caryopsis.
Additional information
-Grasses could also be annual or perennial herbs, generally with the subsequent characteristics.
-The grasses have hollow and cylindrical stems that have apertures at the nodes for the attachment of the leaves.
-Grasses have parallel venation with leaves present in an alternate fashion with two rows that are arranged in the opposite manner.
-The leaf constitutes a leaf blade on the entire leaf margin with a leaf sheath attached to the stem.
-The water or other substances are impervious to the sheath due to the presence of ligule present in between the sheath and the blade.
-The economic importance of Gramineae includes nutrition in the form of food like cereals, sugarcane, etc, having aesthetic values, and medicinal values, etc.

So, the correct answer is ‘Two'.

Note:
The family Gramineae is one of the most widely distributed monocots and are present in a huge number all around the world, even Antarctica. About 12,000 species of grasses are found in the world and they are used widely in the production of beer. The ingredients used for the production of beer are barley or wheat.
