Microbiology test with 100% verified solutions 2024 Bacteria Prokaryotes Generally appear in the shape of Bacillus, coccus and spiral. Form pairs, clusters, chains or other groupings. Enclosed in a protein complex cell wall called peptidoglycan. Reproduced by binary fission, and for nutrition it uses organic chemicals that are derived from other organisms through nature. Many bacteria have flagella Archaea Prokaryotic cells, but LACK peptidoglycan. Found in extreme environments w...

Microbiology pre-assessment final exam 2024 prokaryote with peptidoglycan in their cell walls bacteria What is part of the internal structure of bacteria? endospore cytoplasm ribosome nuclei/chromosome actin cytoskeleton What do Pili participate in? participate in mating process called conjugation, uses pilus as connector for transferring DNA How many layers are in gram positive and gram negative? + = one layer, more penetrable - = 2 layers, less penetrable
