An amoeba and an unlaid chicken egg are

Both an amoeba and an unlaid chicken egg are single cells. An amoeba is a single-celled organism that belongs to the kingdom Protista. It is a type of unicellular organism that moves by extending pseudopods, which are temporary projections of the cell membrane and cytoplasm. An unlaid chicken egg is also a single cell. Before an egg is laid by a chicken, it consists of a single cell called a zygote. This zygote contains all the genetic material necessary to form a fully developed chicken. As the egg is incubated, the zygote undergoes cell division and differentiation, forming various tissues and organs until it becomes a fully formed chick. So, while an amoeba and an unlaid chicken egg are very different from each other, they both start as a single cell.
