Document Summary

Microscopic forms of fungi, algae, and other protists. Three domains of life all come from a common ancestor, which is unknown. Stops growth and development: binary fission, lack membrane bound organelles **, no golgi, er, or chloroplast. Capsule - polysaccharide or protein, stick to surfaces or other cells. Bacteria like form, but have been separated rom the bacteria for a very long time. Some characteristics are more similar to eukaryotes than bacteria. Many species are extremophiles (tolerant to high levels or salinity, heat, cold, osmotic pressure, radiation etc) Termites rely on a community gut organisms to digest the wood they eat. Chlamydia"s - survive in animal cells, dependant on host cell. Chain of green coloured cells -site of photosynthesis -no chloroplast - occurs in the membranes (plasma membrane) many folding"s that carry pigments that resemble thylakoids. Has a clear cell in the middle that is bigger - called the heterocyst - site of nitrogen fixation.
