An embryo (Greek: έμβρυον) is an animal or a plant in its earliest stage of development.

  • Plants: In botany, a plant embryo is part of a seed, consisting of precursor tissues for the leaves, stem (see hypocotyl), and root (see radicle), as well as one or more cotyledons. Once the embryo begins to germinate — grow out from the seed — it is called a seedling.
  • Animals: The embryo of vertebrates is defined as the stages between the first division of the zygote (a fertilized ovum) until it becomes a foetus. An embryo is called a foetus at a more advanced stage of development and up until birth or hatching. In humans, this is from the eighth week of gestation.
