Prokaryotes Prokaryotes are the most abundant organisms on earth. (bacteria and blue-green algae) A prokaryotic cell dose not contain a membranebound nucleus. Size from 0.1 to 10 μm
Three basic shapes 1. I Spherical(coc:球菌) 2. Rodlike( bacilli:细菌,杆菌) 3. Helically coiled( spirilla:螺旋菌) > They fall into two groups: the eubacteria真细菌 and the archaebacteria(古细菌)
