![The phylogenetic Tree of Life. A drawing of branching lines. The central line at the bottom branches into two main branches. On the left branch is a purple branch that contains the following sub-branches: Green filamentous bacteria, Gram positives, Cyanobacteria, Proteobacteria, and Spirocheres. The branch to the right subdivides into a red and a brown branch. The brown branch contains the following sub-branches: Smile molds, Plants, Fungi and Animals. The red branch contains the following sub-branches: Thermoproteus, Methanococcus, Methanobacterium, and Halophiles.]()

![A bar along the bottom indicates size of various objects. At the far right is a from egg at approximately 1 mm. To the left are a human egg and a pollen grain at approximately 0.1 mm. Next is a red blood cell at just under 10 µm. Next is a mitochondrion at approximately 1 µm. Next are proteins which range from 5-10 nm. Next are lipids which range from 2-5 nm. Next is C60 (fullerene molecule) which is approximately 1 nm. Finally, atoms are approximately 0.1 nm.]()
