Prokaryotic Cell Structure
Properties of Cells
- Living entities surrounded by a membrane
- Capable of growth reproduction and metabolism
- Prokaryotes or Eukaryotes
Bacteria Morphology
, Arrangement of bacteria
Strepto = Chain
Diplo = 2
Cytoplasm is the gelatinous material inside the cell
Cytosol
Liquid portion within cytoplasm
Water with dissolved solutes
Contains Nucleoid
DNA
DNA in prokaryotes is negatively supercoiled
Supercoiled is where DNA is wound up very tightly
Positive cupercoil is where DNA Coiled in the same direction of DNA Helix
Negative supercoil is DNA is coiled against the direction of DNA helix
Plasmids
Separate from the core bacterial genome
Can carry beneficial genes (eg. Resistance genes)
Not all bacteria carry plasmids
Ribosomes
Protein synthesis
