Document Summary
All life on earth consists of 2 types of cells: eukaryotic & prokaryotic: eukaryotic (more complex, humans, millions of species, single or multi-celled, nucleus & other organelles, larger (10x), more complex, protists, plants fungi, & animals, approx. 2 billion years old: prokaryotic, single celled, no nucleus or organelles, smaller, less complex, eubacteria, archaea. 3 domains of living organisms: bacteria- prokaryotic, archaea- prokaryotic, eukarya- eukaryotic. Fungi- absorbs food, breaks down on outside of body & absorbs goo: eukarya (membrane bound organelles, kingdom protista, eat, absorb, kingdom fungi, absorption, kingdom plantae, photosynthesis, kingdom animalia. 13. subatomic- proton, neutron, electron: physics, chemistry, biology. The science of biology: all events can be attributed to natural causes, natural laws apply at all places and all times, people perceive events in similar ways. Atom: the basic structural unit of matter i. e. - the smallest pieces of stuff, protons- positive, neutrons- none, electrons- negative, electron shells: (1) 2, inert- won"t react.
