The Classification of Organisms

I am beginning to add some to Kingdom Plantae, but most of my lists are in the Kingdom Animalia, close to the bottom of the list. Things will change, but slowly.

I also have a glossary to help you with terminologies.

For information on where I got my information, see the bibliography.
