Divergent Event: Research shows that about 3 billion years ago, Eubacteria split from Archaebacteria.
Body Plan:Unicellular
Metabolism: They are both heterotrophic and autotrophic.
Digestion: Intracellular
Nervous: None
Circulatory:None
Respiratory: They can be aerobic and anaerobic. Anaerobes go through fermentation.
Reproduction:They are asexual and go through mitosis or meiosis
Examples:
Proteobacteria-The Proteobacteria kingdom is the largest and most diverse in Bacteria. These organisms show extreme metabolic diversity and represent the majority of known gram-negative bacteria of. May have gas vesicles, flagella, or can move by gliding. Some species are able to carry out photosynthesis. Ex).Alphaproteobacteria-

Gammaproteobacteria-

Chlamydias-Is a harmful bacteria that is a Sexually Transmitted disease.Chlamydia may be found in the form of an elementary body and a reticulate body. The elementary body is the non-replicating infectious particle that is released when infected cells rupture. The elementary body is responsible for the bacteria's ability to spread from person to person. It is gram-negative.

Spirochetes- They are gram-negative, they have spiral shaped coils. They are chemoheterotrophs. They are anaerobic and asexual. Leptospira

Cyanobacteria-Also known as blue green algae, obtain energy through photosynthesis. Chloroplasts may have emerged due to endosymbiosis. Found in many aquatic areas.

Gram-Positive Bacteria- Most are chemoheterotrophs, there are few photosynthetis gram-positives. They contain more peptidoglycan. They produce endospores.
