Endosperm is the tissue produced inside the seeds of most flowering plants around the time that the egg (seed) is fertilized. It surrounds the seed embryo and provides nutrition in the form of starch, and can also contain oils and protein. This makes endosperm an important source of nutrition in human diet. For example, wheat endosperm is ground into flour for bread.

What is the difference between a zygote and an endosperm?
i)A zygote if formed due to the fusion of two gametes while endosperm is not from the fusion of two gametes. ii)A zygote is of 2n condition while endosperm is of 3n condition iii)A zygote later develops to a plant while endosperm provides nourisment to it. iv)After fertilization it is a fact endosperm develops first then zygote so that the zygote gets the nourishment sufficiently.
What is the ploidy of cells of aleurone layer in cereal grains?
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
What are the components of a typical seed?
Testa, Tegmen, Embryo (Plumule and Radicle) , Endosperm, coleoptile, etc
What are three characteristics of grain?
Three key characteristics of grain are its nutritional composition, which typically includes carbohydrates, proteins, and dietary fiber; its physical structure, often comprising a hard outer shell (husk), a starchy endosperm, and a nutrient-rich germ; and its versatility in cooking and processing, allowing it to be used in various forms such as flour, whole grains, and cereals. Additionally, grains can vary in color, size, and flavor, influencing their culinary applications.
What is the function of the cotyledons?
it stores food for the young plant and also protect itAnswer:It's a principle part of the embryo in the seed of a plant. Seeds with two are called dicotyledons, seeds with only one are called monocotyledons.
Name an example of a seed that has liquid endosperm?
An example of a seed that has liquid endosperm would be a coconut. While it does contain cellular endosperm, the coconut milk would be considered liquid endosperm.
Once fertilized the central cell becomes?
the endosperm
What is a food-rich tissue that nourishes the seedling as it grows called?
endosperm
What do the result of the iodine test indicate about the composition of the endosperm?
The result of the iodine test indicates the presence of starch in the endosperm. When the endosperm is stained blue-black by iodine, it suggests a high starch content. Conversely, if there is little to no staining, it indicates a low starch content in the endosperm.
Is there is endosperm present in gymnosperm?
No, triploid endosperm is in angiosperms only. Gymnosperm means "Naked Seed."
What is the 3n nutritive tissue in the seed of angiosperms called?
the triploid The endosperm is a nutritive tissue which nourishes the developing embryo. The endosperm in angiosperm is triploid (3n) and it is a post - fertilization structure.
What are the uses of the endosperm portion of the wheat kernel?
White flour is made only with the endosperm portion of the wheat kernel. Farina is also made from the endosperm, but it is ground to produce a granular product.
What feeds the plant embryo?
The plant embryo is nourished by the endosperm, which is a tissue rich in nutrients that surrounds and supports the embryo during seed development. The endosperm provides essential carbohydrates, proteins, and lipids for the growing embryo until it can establish its own root system and begin photosynthesis.
What part of the grain that remains after being refined?
The part of the grain that remains after being refined is the endosperm.
What is endosperm haustorium?
The endosperm haustorium is a structure formed by the developing embryo in some plant species to absorb nutrients from the endosperm. It allows the embryo to obtain essential nutrients for its growth and development during seed germination. The endosperm haustorium eventually withers away as the embryo becomes self-sufficient.
Seedling is nourished by what?
the endosperm
What is ploidy of the endosperm?
3n
