Document Summary

Bisc 101 lecture 3 a tour of the cell: part i. Ex: bacteria and archaea: eukaryotes: contain a membrane bound nucleus. Differences between prokaryotic and eukaryotic cells: eukaryotic chromosomes and dna are found inside a membrane bound compartment called nuclear envelope where the nucleus is; plasmids are rare. Prokaryotes have chromosomes in a non membrane bound nucleoid since there is no nucleus; plasmids are very common: eukaryotic cells are much larger than prokaryotic cells, eukaryotic cells contain a lot of membrane bound organelles. No membrane bound organelles: eukaryotic cells have a dynamic cytoskeleton found throughout the cell. Limited in extent for prokaryotes: dna is packaged as multiple linear chromosomes. Prokaryotes have dna packaged as a circularly arranged chromosome: cytoplasm in the region between the plasma membrane and nucleus. Cytoplasm only bound by the plasma membrane since there is no nucleus: eukaryotes divide by a process called mitosis. Prokaryotes divide by a process called binary fission.
