Arranged the organisms in a way they could be easily identified by using more groups then just plants and animals, basing his system on specific traits, and gave the organisms names that described their traits.

How are the system of categories organized? How does this make things easier?
From broad to specific. Having so many categories makes it easier to place an organism correctly.
What are monera?
Single celled organisms that do not have a nucleus (eubacteria and archaebacteria)
What are protists?
Either single celled organisms that do have a nucleus or some simple multicellular organisms
What are fungi?
