What is the largest group of bacteria?
The largest group of bacteria is known as Proteobacteria, which includes a wide range of diverse bacterial species with various shapes, sizes, and metabolic functions. Proteobacteria are found in various environments, including soil, water, and the human body.
What does the theory of endosymbiosis explain?
concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

Is alpha proteobacteria gram negative?
Yes, alpha proteobacteria are generally Gram-negative bacteria, characterized by the presence of a thin peptidoglycan layer in their cell envelope. They are a diverse group of bacteria found in various environments, ranging from soil to symbiotic relationships with plants and animals.
Some of the functions of the eukaryotic organelles are performed in bacteria by the?
Some functions of eukaryotic organelles, like photosynthesis in chloroplasts and energy production in mitochondria, are performed by bacteria such as cyanobacteria and proteobacteria. Bacteria can also carry out protein synthesis similar to the endoplasmic reticulum in eukaryotic cells.
What process is thought to be involved in the genesis of eukaryotes from prokaryotes?
It is almost certain that DNA-bearing organelles like the mitochondria and the chloroplasts are what remains of ancient symbiotic oxygen-breathing proteobacteria and cyanobacteria, respectively, where the rest of the cell seems to be derived from an ancestral archaean prokaryote cell - a theory termed the endosymbiotic theory.
What is the common name for Proteobacteria?
The common name for Proteobacteria is simply "proteobacteria."
What is the phylum of salmonella?
Gammaproteobacteria
What might mitochondria descended from?
Mitochondria are believed to have descended from ancient bacteria known as alpha-proteobacteria through a symbiotic relationship with early eukaryotic cells. This symbiotic relationship eventually led to the integration of the alpha-proteobacteria into the host cell, resulting in the formation of mitochondria.

What major group of bacteria does Rickettsias belong to?
proteobacteria
Is Rhodospirillum a eukaryote?
No, Rhodospirillum is not a eukaryote. It is a type of bacteria that belongs to the phylum Proteobacteria. Eukaryotes are organisms with cells that have a nucleus and other membrane-bound organelles, which bacteria like Rhodospirillum lack.
Is proteobacteria Autotrophic or Heterotrophic?
Proteobacteria are typically heterotrophic, meaning they obtain their energy by consuming organic compounds. However, some proteobacteria are also capable of being mixotrophic, meaning they can switch between autotrophic and heterotrophic modes of nutrition.
What diseases caused by proteobacteria?
Some diseases caused by proteobacteria include cholera (Vibrio cholerae), whooping cough (Bordetella pertussis), and gastric ulcers (Helicobacter pylori). Proteobacteria are a diverse group of bacteria that can cause a range of infections in humans and animals.
What is the scientific name for proteobacteria?
The scientific name for Protococcus is Protococcus viridius Agardh. The classification of protoccocus is: Plantae, Viridaeplantae, chlorophyta, clorophytina, trebouxiophyceae, chlorellales, ctenocladaceae.
What class is escherichia coli in?
the class Escherichia coli's in is gamma proteobacteria.
