Term | Definition |
Passive | Diffusion, Osmosis, Facilitated |
Active | Endocytosis, Exocytosis |
Solvent | Liquid-usually water |
Solute | Other Material |
Cell size | very small |
Cell shape (morphology | Coccus, Bacillus, Spiral/curves |
Coccus | round, spherical, oval |
Bacillus | Rod, short rods that have roundness, Pill, coccobicillus |
Spiral/Curves | Vibrios, Spirillum, Spirochete |
Groupings | Chain, Packet, Cluster/Irregular |
Growth Media | Slant tube, Broth tube, Plate |
Lag phase | Bacteria is just getting use to new home, make molecules needed to start growing, Lenght of time in this phase depends upon amount of nutrients |
Exponential phase | Cells dividing at even rate, focus on cell numbers, cells at risk, cells making variety of molecules: ex proteints, amino acids, toward end of this phase thins start to slow down |
Stationary phase | Energy and nutrients are almost gone, cell growth=cell death |
If nutrients are pretty much gone how can some cells keep growing | Go canibal |
Death phase | Cells are dying at a constant but slow rate, no reproduction |
Prolonged decline | Interesting a small number are still alive living off of their family....fight to the finish, can only be days, can be years |
Environmental Factors | Temperature, oxygen, pH, water |
