Document Summary
Animals: can move around, have a soul. Plants: every other living thing, have bodies but don"t move. Thermophiles: in very hot temperatures (volcanic vents) Methanogens: live in anaerobic guts (oxygen is poisonous to them; produce methane as a waste product), and also include true extremophiles. Highly valuable for molecular biology, such as resolution of the tree of life. Cyanobacteria (blue-green algae) are capable of photosynthesis and. In human gut, many bacterial cells help with the digestive system nitrogen fixation. Led to oxygen-rich atmosphere 1. 8 billion years ago. Autotrophs: generate food from inorganic carbon (carbon dioxide) Heterotrophs: feed on organic substances (other organisms or their products) for both energy and carbon source. Eukarya (recognized as more diverse than before) Closely related to animals more than photosynthetic clades. Can exist in both multi and unicellular forms. Interconnected in a network that makes up the main body of. Tubular filaments of high surface area/volume ratio. Keep it from bursting from to osmosis.
