embryo

The Planarian Anatomoy Ontology (PLANA) is a collection of terms curated from the literature and other organism anatomy ontologies to describe anatomical features, life cycle stages and developmental processes in the regenerative flatworm Schmidtea mediterranea. The latest version of the PLANA Ontology is available through the Open Biological and Biomedical Ontology Foundry (OBO) . PLANA Ontology terms are searchable at the EMBL-EBI Ontology Lookup Service (OLS) and the PLANA Ontology Terms Page.

The Overview Section is populated with infomration from the OLS.




Planarian Anatomy Ontology Term Overview


NAME:

  embryo


DEFINITON:

  Anatomical entity that comprises the organism in the early stages of growth and differentiation that are characterized by cleavage, the laying down of fundamental tissues, and the formation of primitive organs and organ systems. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant.
