BIOS 111 Chapter Notes - Chapter 4: Streptococcus Pneumoniae, Glycocalyx, Basal Body
Document Summary
Bios 111 chapter 4 - anatomy of prokaryotes and eukaryotes vocab/notes. Fungi, yeast, mod, protozoa, and algae are eukaryotes. Most bacteria are found sticking to solid surfaces, held by glycocalyx which is the glue the holds it down. They both contain nucleic acids, proteins, lipids, and carbohydrates. They both make energy and protein similarly. Dna is not enclosed in a membrane; it is a singular, circularly arranged chromosome. Dna does not have histones associated with it. Binary fission: dna is copied and cell splits in two. Dna found in nucleus, which is separated from cytoplasm. Dna is associated with histones and nonhistones. Have simple cell walls, if they have cell walls. Bacteria are differentiated by morphology, chemical composition, nutritional requirements, biochemical activities, and energy sources. Biofilm: group of microorganisms stuck to each other and a surface. Bacteria basic shapes: spherical coccus, rod-shapes bacillus, and spiral. Cocci are round but can be oval, long, or flat on one side.
