|
|
|
Culture |
Cells grown in/on nutrient medium |
Microbio, 2 parts |
|
|
Medium |
Liquid/solid mixture containing all required nutrients (for cell growth) |
Noun |
|
|
Growth |
Increase in cell number resulting from cell division |
Can occur on micro meter scales (i think) |
|
|
Colony |
Visible; contains millions or billions of cells |
Visible often on millimeter scale |
|
|
The cell |
A living compartment that interacts w/environment & other cells. Common elements: cytoplasmic membrane, cytoplasm, ribosomes, *some have cell wall |
|
|
|
Cytoplasmic (cell) membrane |
Barrier separates inside of cell from outside environ |
|
|
|
Cytoplasm |
Aqueous mix of macromolecules, smol organics, ions, and ribosomes inside |
Inside of cell |
|
|
?Ribosomes |
Protein synthesizing structures |
|
|
|
Cell wall |
Present in sone microbes, confers structural strength |
|
|
|
Prokaryotic cells |
No organelles (membrane-enclosed structures) no nucleus, typically dna =small (<10mil bps), 1 circular chromosome, can have extra plasmids w/ dna too |
Bacteria and archaea |
|
|
Eukaryotic cells |
Contain organelles, dna enclosed in membrane bound nucleus, mito and chloroplasts, dna = linear, larger/more than pros- bills of bp |
Examples: plants, animals, algae, protozoa, fungi |
