1. Eukaryotic Cells 1. nucleus present in enclosed membrane
general facts 2. membrane bound organelles (ex. mitochondria or ER)
3. Large ribosomal subunit (80S: 60S + 40S subunits)
4. linear and mutiple chromosomes
5. Cell division via mitosis and meisosi
6. Cell wall composed of cellulose or chitin in plants/fungi
7. typically larger
2. prokaryotic cells 1. Absent nucleus
general facts 2. no membrane-bound orgnalles
3. smaller ribosomal subunit (70S: 50S and 30S subunits)
4. circular, usually one chromsome
5. cell dvision via binary fission
6. cell wall composed of peptidogylcan (if present)
7. typically smaller
3. Eubacteria (true 1. cell wall contains peptidogylcan
bacteria) general 2. membrane lipids are fatty acids with ester bonds.
facts 3. found in diverse environments
4. can cause disease in humans
4. Archaea general 1. Cell wall has no peptidoglycan, uses pseudopeptidogylcan
