Document Summary
Many prokaryotes can tolerate extreme conditions as well as normal habitats ability to adapt to broad range of habitats is reason why they are the most abundant organisms on earth. 27. 1 structural and functional adaptations contribute to prokaryotic success. The first organisms to inhabit earth were most likely prokaryotes. Typically have a diameter of 0. 5-5um vs the 10-100um of eukaryotic cells. Well organized able to conduct all life functions within a single cell. Cocci spherical prokaryote: appears singularly, in pairs (diplococci), in chains of many cells (streptococci), in clusters (staphylococci) Bacilli rod-shaped prokaryote: usually solitary or in chains (streptobacilli) Spiral prokaryotes comma-like shapes or loose coils: spirochetes corkscrew-shaped. Key feature of prokaryotic cells is the cell wall which: maintains cell shape, protects the cell, prevents it from bursting in a hypotonic environment. Eukaryote cell walls are made of cellulose or chitin. Gram stain technique developed by hans christian gram to classify bacterial species based on cell wall compositions.
