Document Summary
Archaea: pm more complex, flagella is thinner. Bacteria and archaea: prokaryotes, very small, single- celled. Prokaryotes are classified by shape and movement (locomotion), pigmentation, staining techniques, nutrients, colony appearance: common shapes, spherical, rod-shaped, corkscrew-shaped, locomotion, flagella. Viruses, virads, prions: attaches to the host cell, release its genetic material (dna, rna)- nucleus, enter cytoplasm and makes viral proteins, exits cell (cell dies, viral proteins are replicated ( increase in symptoms) 19. 1 which organisms are members of the domains archaea and bacteria: earth"s first organisms were prokaryotes, single-celled microbes that lacked, prokaryotes are still abundant, forming two of life"s three domains organelles. Archaea: bacteria and archaea are fundamentally different, they have some similarities. They are both single-celled organisms: differences between bacteria and archaea, structural and biochemical features. Bacteria have peptidoglycan in their cell walls; archaea don"t. There are also differences in the plasma membrane composition, ribosomes, and. Differences in transcription and translation also exist between the two.
