Egg

An egg is a reproductive cell produced by female animals, most commonly by birds like chickens. It consists of a protective shell, often calcium carbonate, encasing the yolk and white, which provide nutrients. The yolk contains fats, proteins, and vitamins, serving as a food source for developing embryos if fertilized. Eggs are a vital source of protein and other nutrients for humans and many animals. They are widely consumed worldwide in various culinary applications and are also used in baking, cooking, and food manufacturing.
