| | An '''egg''' is a reproductive capsule produced by many animals to reproduce. Fertilized eggs contain [[embryo]]s which develop into whichever [[animal]] laid it. Some animals have eggs which are only visible at a [[cell]]ular level, like humans for example. Usually the egg contains all the [[nutrient]]s the developing animal needs, but mammals some develop within their mothers (such as mammals), almost eliminating the need for eggs. Most eggs are considered tasty, such as [[chicken]] eggs, but they tend to [[rotting|rot]] after a short amount of time unless kept [[cold]]. However, eggs, almost entirely in their yolks, provide excellent sources of nutrition due to their abundance of vitamins and minerals, particularly several fat-soluble vitamins less prevalent among plant-based foods; vitamin D3, naturally exclusive to animal products, are found in egg yolks. | | An '''egg''' is a reproductive capsule produced by many animals to reproduce.
