BIOL 1002 : Biology Test 1
Document Summary
Taxonomy- the branch of biology concerned with naming and classifying the diverse forms of life on our planet. Now there are 3 domains: the 3 domain and the kingdoms within them each have observably different attributes that define them: bacteria - prokaryotes, archaea- prokaryotes, eukarya- animals, fungi, plants, protists. (eukaryotes) If a species is single celled it is grouped with the protists. Organisms which were once placed together in a certain classification group have been separated when new or better evidence is uncovered. Biodiversity: one thing is very clear, the more biologists look, the more species are found. There are about 1. 4 million identified species and possibly 5 to 75 more which have not been classified. (100 million) Must get into a host cell to replicate. Microbe: too small to be seen clearly without a microscope: prokaryotes- range in size from 0. 2-1. 0 micrometers, unicellular eukaryotes- range in size from 10-100 micrometers.
