The part that separates the embryo region from the endosperm region in the seed of maize is the
A) Scutellum
B) Husk
C) Testa
D) Hilum
Solution
Endosperm is a tissue that is usually produced inside a developing seed usually in flowering plants. It is a triploid that consists of 3 sets of chromosomes. Endosperm provides nourishment to the developing embryo. It contains starch protein oil.
Complete answer:
The seed consists of an outer aleurone layer that is usually followed by inner starchy endosperm. The major function of the aleurone layer is to provide important digestive function, helps in secretion of hydrolases which break down the starch and proteins stored in the starchy endosperm cells.
The endosperm stores food, consisting primarily of starch, protein and oil. The seed is covered by one or two layers which protects the seed from harsh conditions. Seeds form an embryo after fertilization. Here is a diagrammatic representation of a seed.
Scutellum is usually found in rice and barley seed. It is a thin layer between embryo and endosperm which absorbs nourishment from the endosperm and provides to the developing embryo.
So, here the correct answer would be option A.
Note:
Scutellum is a Latin world that means “small shield”. The scutellum is believed to be a modified cotyledon, or seed leaf. In grasses this seed leaf serves to digest endosperm and transfer nutrients to the embryo. It is mostly present in monocotyledons.
