Taxonomy and the tree of life.
HS Biology Taxonomy
Overview
A brief lesson on Taxonomy using the 5 Kindom classification system, along with phylogenetic tree.
5 Major Kingdoms
The classification Kindoms begin with single-cell Prokaryotic organisms (Monera) and pass through simple Eukaryotic organisms (Protista) then culminate in the trhee multicellular organisms (Fungi, Plantae, and Animalia). In this system all bacterias have been filed together in Monera. Monerans were very hard to differentiate since they don't have many structures to look at, until DNA, RNA, and proteins could be studied. Over 10,000 different species of Monerans have been identified. Organisms in the Kindom Protista are there because they lacked any characteristics that would allow them to be placed in any of the other four Kingdoms. About 100,000 species of protists have been identified. Fungi were originally classified as plants, but scientists have reclassified them into their own Kingdom and differentiate them by the structures they use for reproduction. Around 100,000 species of Fungi have been identified to date. There are over 260,000 species of plants in the Kingdom Plantea. These can be divided into two broad groups, vascular and non-vascular, with most plants falling in the vascular category and being distinguished by their very different physical characteristics. Taxonomists have suggested that there are at least 800,000 and as many as 12 million species in the Kingdom Animalia.Scientists have proposed more than 30 animal Phyla.
