The term egg , which comes from the Latin word ovum , refers to a rounded element produced by females of various species that shelters the germ of an embryo and stores the substances that nourish it during incubation.
The hardness and size of the egg depend on the type of animal . This structure arises when the fertilization of the egg occurs and the embryo must be protected and receive nutrients. Birds and numerous reptiles , amphibians , fish , arachnids and insects reproduce in this way.
Eggs have a shell or shell that is the first layer of protection. Inside are the white (made up of proteins and water) and the yolk (which contains the yolk - the sector of the cytoplasm of the zygote that contains lipids, carbohydrates and other nutritional substances - and the germinal disc). The white is the white part inside the egg; the yolk, the yellow portion.
Most animals usually hatch or incubate the eggs by warming them . Within the framework of this process the zygote develops. When the embryo reaches the necessary development, the egg hatches : the shell breaks and the specimen is born.
It should be noted that bird eggs are a very important food for humans . The most consumed are chicken eggs , although quail eggs , goose eggs and duck eggs are also popular.
Eggs can be eaten in multiple ways: fried, scrambled, boiled, etc. They are also used to prepare tortillas , biscuits, mayonnaise and many other products.
