Kingdom monera characteristics

Kingdom Monera

Kingdom Monera Characteristics:5 main characteristics of bacteria:1. Prokaryotes This is the only prokaryotic kingdom2. Unicellular3. No membrane bound organelles in cytoplasm4. Single circular chromosome5. Reproduces by binary fission “splitting in two”

Diagram of a typical bacterial cell Pili = for movement Cell wall = structure,

support, & protection of bacteria

Cytoplasm = fluid part around organelles

Ribosome = make proteins

Flagellum = some have these for movement

Chromosomes = circular DNA – genetic information

Archaebacteria: Resemble 1st life forms on earth – primitive Able to live in extreme conditions =

extremophilesThermophiles – extreme temperatureHalophiles – very saltyAcidophiles – very acidicAlkaliphiles – very basicMethanogens – methane gas

Eubacteria:

Largest group of Monerans Majority of bacteria Most are decomposers / heterotrophs /

saprophytes Some photosynthesize like cyanobacteria

or chemosynthesize
