A plant embryo is a young and developing plant. An example of this includes a rudimentary plant inside the seed of a higher plant or located in the archegonium inside a moss or fern.
Plant embryology, or the development of a full-grown plant from an embryo, contains some elements of development that is seen in different types of animals. There is an egg and a sperm which unite to form the fledgling zygote. The seed-bearing organ of the plant is termed the pistil. It is there where the egg is located. Sperm reaches the egg by traveling down a tube.
