- Embryology and Ontogeny. Ontogeny is the development and changes that an embryo goes through as it changes from the fertilized egg to the organisms’ mature form.

What are the three classifications of organisms?

What are the three currently recognized domains used in taxonomy?
The three-domain system is a biological classification introduced by Carl Woese et al. in 1990 that divides cellular life forms into archaea, bacteria, and eukaryote domains. The key difference from earlier classifications is the splitting of archaea from bacteria.
What Three characteristics are used to classify an organism into a kingdom?
Organisms are placed into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.
