Question

What is seed? Define scutellum.

Answer 1

Hint: In flowers producing plants such as angiosperms and gymnosperms, once fertilization happens by the pollen and ovule, seeds are formed, and it is considered as ripened ovule, where some part of growth occurs in the mother plant, and the scutellum is the one of structure or part of the structure of seed, where it is also named as modified seed leaf.

Complete step by step answer: It is an embryonic plant that is enclosed in a protective outer covering and the formation of seeds is a part of reproduction.
They play an important role in the growth and development of reproduction and the success of angiosperms and gymnosperm plants.
In some primitive plants like ferns, mosses, liverworts, those are first formed vascular plants and they don’t seed, where they generally propagate themselves.
The general meaning of a seed is that anything that can be sown examples include, seeds of corn and sunflower seeds, etc.
Seeds have many functions which include, nourishment, and dispersion, and the dormancy In case of unfavorable conditions, etc.
Scutellum: Scutellum is a part of the structure of a seed, which is called a modified seed leaf.
The scutellum is also called as. Or equal to a thin cotyledon in monocots, it is very thin which has a high surface area, and it also serves to absorb nutrients from the endosperm, during the germination of seed.
At the same time scutellum acts as unidentified protein transports which facilitates the movement of starch from endosperm to embryo.
In the grass, these seed leaf or scutellum never develops into the green structure, but it serves only to digest endosperm and it transfers nutrients to the rest of the embryo.

Note: In some flowering plants such as angiosperms, seeds contain different genetic constituent cells, which are an embryo, formed by the zygote and the endosperm which is generally triploid, and the seed coat that is derived from maternal tissues. When coming to scutellum, it generally arises from octane cells, where some part is contributed by cotyledon.
