Sorry, no etymologies found.
The endosperm is more finely ground, but the germ and bran are ground separately and coarser and then it is all brought back together.
The endosperm is the food store for the developing seedling.
Popcorn pops because the pericarp is strong enough to hold in the steam created when the endosperm, which is 14.5 percent water, is heated — strong enough, that is, until the steam reaches 177 degrees C. and the pressure builds to 9.5 kilograms per square centimeter.
In this way the starchy, carbohydrate-rich center, called the endosperm, is separated from both the dark, fibrous bran and the wheat embryo, called the wheat germ.
The endosperm from the Greek: “within the seed” is often the only part of the grain consumed.
• Flour corns, including the standard varieties of blue corn, are soft and easily ground because their endosperm is a discontinuous and weak combination of relatively little protein, mostly waxy starch, and air pockets.
This fine white powder called “flour” is, in fact, the ground endosperm, which is about 67 percent carbohydrate, 9 percent to 14 percent protein, and the rest water The amount of protein in flour can vary according to what kind of wheat is used.
_Balanophora_, the embryo is developed from a cell of the endosperm, which is formed from the upper polar nucleus only, the egg apparatus becoming disorganized.
The endosperm-nucleus divides rapidly to produce a cellular tissue which fills up the interior of the rapidly-growing embryo-sac, and forms a tissue, known as endosperm, in which is stored a supply of nourishment for the use later on of the embryo.
The macrospore or embryo-sac produces a prothallium called the endosperm, in which archegonia or corpuscula are formed; and lastly, in typical dicotyledons it is only lately that any trace of a prothallium from the microspore or pollen cell has been discovered, while the macrospore or embryo-sac produces only two or three prothallium cells, known as antipodal cells, and two or three oospheres, known as germinal vesicles.
