(c) Awn is present on paleo
(d) Tetramerous

Answer 1

The flower of Poaceae 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 grunge flower has similar characteristics to the Poaceae family. It has palea as a bracteole in its flower. The bracteole is a leaf-like structure which is small in size and is attached to the flower or inflorescence and its stalk is extended to form the bract. The bract is the extended part of a single flower, not the whole inflorescence.
The largest number of species of flora in India are from the family Poaceae, 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 needed, the fruit is single-developed with the testa adnate to the pericarp, a caryopsis.

Note:
The grunge flowers are generally used as an aesthetic and are used for the purpose of decorations. They are of various colors, shapes, and sizes and can be designed differently as per the wish. The flower may consist of 4 or more petals with varied colors.
