Microbiology - Monera (bacteria)
Characteristics of Kingdom Monera
Bacteria are found in salt water, fresh water, soil, dust, air, plants and animals
They are small
single-celled
organisms
Found in extreme environments sch as high temperatures and low ph
Motile
due to their
flagellum
Prokaryotic
Contain DNA plasmids
Unicellular
No mitochondria
Structure of Bacteria
DNA plasmid
Made Of:
DNA
Function:
Special ability = can develop a resistance to antibiotics
Ribosomes
Function:
Protein synthesis
Made Of:
RNA + protein
Nuclear material
Made Of:
Arranged into circular chromosomes (nucleoid)
Function:
Reproduction genes
Storage Granules
Made Of:
Condensed materials
Function:
Storage of condensed materials
Cell Membrane
Made Of:
Phospholipid bi-layer (phosphates + lipids), proteins
Function:
Controls what enters and leaves bacterium
Flagellum
Made Of:
Protein
Function:
Enable movement = motility
Cell wall
Made Of:
Cellulose
Function:
Gives structure to bacteria
Mesosome
Function:
Helps in synthesis of cell membrane, replication of DNA and protein synthesis
Capsule
Made Of:
Polysaccharide = Chitin
Function:
Acts as an extra layer of protection
Classification of Bacteria
Rod/bacillus
Spirals/spirillium
Round/coccus
