What are the 5 types of bacteria?
Bacteria are the plural of bacterium, which are microscopic one-celled organisms.
They are found everywhere and can be harmful, as in infections; or they can be beneficial, as in fermentation or decomposition.
Five types of bacteria are: Coccus, Bacillus, Spirillum, Rickettsia, and Mycoplasma..
Is a virus a life form?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
What is the oldest living being on earth?
Great Basin Bristlecone pine treeHowever, the oldest, precisely measured organism living on Earth today remains, for now, a Great Basin Bristlecone pine tree. Pando the quaking aspen and Antarctic glass sponges could be much older but their ages are assumed from indirect measurements and educated guesswork.
What is the longest living bacteria?
Permian Bacteria In late 2000, scientists reported that they had revived four unknown strains of bacteria from the Permian era, about 250 million years ago. These Permian bacteria are now considered the oldest living organisms ever discovered in the world.
What came first bacteria or virus?
Viruses did not evolve first, they found. Instead, viruses and bacteria both descended from an ancient cellular life form. But while – like humans – bacteria evolved to become more complex, viruses became simpler.
Who found bacteria?
Antoni van LeeuwenhoekTwo men are credited today with the discovery of microorganisms using primitive microscopes: Robert Hooke who described the fruiting structures of molds in 1665 and Antoni van Leeuwenhoek who is credited with the discovery of bacteria in 1676.
How much of the earth is bacteria?
Our science editor Dr David Whitehouse reports. The scientists from the University of Georgia estimate the number of bacteria on our planet to be five million trillion trillion – that’s a five with 30 zeroes after it. There are far more bacteria on earth than there are stars in the universe.
Do viruses move?
How do viruses multiply? Due to their simple structure, viruses cannot move or even reproduce without the help of an unwitting host cell. But when it finds a host, a virus can multiply and spread rapidly.
What was the first bacteria on Earth?
Cyanobacteria, also known as blue-green algae, started out on Earth quite a while ago. Possible fossil examples have been found in rocks that are around 3500 million years old, in Western Australia.
What is the oldest cell in the world?
Scientists say they have discovered 3.4-billion-year-old cells, possibly the oldest fossils ever found.
Which animal has longest lifespan?

Who is the father of viruses?
Martinus BeijerinckFather of Virology Sadly, he did not live long enough to actually see his virus particles under the electroIn 1905n microscope or learn how widespread and important they are. Martinus Beijerinck is often called the Father of Virology.
Where did the first virus come from?
Viruses may have arisen from mobile genetic elements that gained the ability to move between cells. They may be descendants of previously free-living organisms that adapted a parasitic replication strategy. Perhaps viruses existed before, and led to the evolution of, cellular life.
