UCF Biomedical Sciences Exit Exam Study Guide With Questions And
100% SURE ANSWERS
Terms in this set (54)
- nucleus
- membrane bound organelles
- Larger, complex, mostly multicellular
- DNA is linear in chromosomes
eukaryotic cells - DNA tightly wrapped around histone proteins (chromatin)
- mRNA is edited
- replicate through mitosis and meiosis
- free and bound ribosomes
- 80S ribosomes
, 8/13/24, 7:11 PM
- smaller, less complex
- no membrane bound organelles
- no nucleus
- DNA is circular, not packaged as chromosomes
prokaryotic cells - no histones
- mRNA usually unedited
- replicate through binary fission
- free ribosomes
- 70S ribosomes
- Domain of unicellular prokaryotes whose cell walls are made up of peptidoglycan
Eubacteria - thrive in normal conditions
- lipid bilayer as cell membrane
- Domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan (pseudo)
Archaea - thrive in extreme conditions
- lipid monolayer in cell membrane
a dormant, tough, and non-reproductive structure produced by certain bacteria (gram pos) typically
endospore
due to lack of nutrients/periods of stress
capsules protect a bacterial cell from ingestion and destruction by white blood cells (prevent phagocytosis)
long, whip-like filament that helps in cell motility. Many bacteria are flagellated, and sperm are
flagella
flagellated.
- thick peptidoglycan layer
- no outer membrane
gram positive
- contain teichoic acids
- stain purple/blue
- thinner layer of peptidoglycan
- has outer membrane
gram negative
- contains lipopolysaccharides
- stain pinkish/red
1. lag phase = population remains constant, metabolically active, cells grow in size
2. log phase = cell population size increases logarithmically as cells begin to reproduce
microorganism growth phases
3. stationary phase = population size is constant, though some cells are dying and others are dividing
4. death = total lack of nutrients and reproduction stops; death rate exceeds division rate
