Question

A typical monocot seed doesn't have
A. Coleorhiza
B. Coleoptile
C. Bract
D. Scutellum

Answer 1

Hint:- Monocot defined as the grass or grass-like flowering plants which means angiosperms, the seeds of which generally comprise only 1 embryonic leaf or cotyledon. It is composed of one of the main groups in which the flowering plants have been divided traditionally while the remaining of the flowering plants have cotyledons. So that they are categorized as dicots or dicotyledons.

Complete answer: Coleorhiza is defined as the structure which covers the root apex in the case of monocots. It is a sheath-like structure found in a plant seed that attaches the coleoptile to the main root and behaves as a protecting coating surrounding the plumule and radicle.
Coleoptile is defined as the ensuring sheath covering the emerging shoot in monocots like in grasses in which barely any leaf primordia and shoot apex of monocot embryo stay encased.
It stops growing when it arrives at the ground and the standard leaves perforate at its top and continue to grow along.
A bract is characterized as the specific leaf, especially one that is connected with a regenerative structure, for example, a bloom, inflorescence hub, or cone scale, however, not with seed.
Scutellum comes from the Latin word scutella which means "small shield that absorbs nutrients from the endosperm during germination because this is a very thin structure and has a high surface area.
It is a modified seed leaf in the case of monocots like in barley and rice seeds.
So, the correct answer is (C) i.e. Bract.

Note:- Monocot comprises approximately 60,000 species. It produces the majority of biomass in the field of agriculture. Orchid is the biggest group of a monocot or in the blossoming plants. It involves about in excess of 20,000 species.
