Document Summary

Be able to apply all the bolded terms in the phylogeny section of lab 1 to a cladogram. Better to just read this yourself, these aren"t just definitions, you need to look at them on the example cladogram given: cladogram: phylogenetic tree, lines of a cladogram = lineages. Know the three domains of life (bacteria, archaea, eukarya) and traits that distinguish these groups from each other. Includes over 4,600 described species of small, mostly unicellular organisms. Cells of bacteria and archaea have an outer cell wall lined inside by a plasma membrane that encloses cytoplasmic contents including dna, ribosomes, and a myriad of enzymes that function in chemical reactions. Lack nuclei or any membrane bound organelles. Lack cytoskeletal elements or certain contractile elements. Dna consists of a circular strand that is not associated with histone proteins and does not form chromosomes. Reproduction by fission (does not undergo meiosis or mitosis)
