Classification of organisms
Bacteria
Roles in humans
The bacteria in our bodies help degrade the food we eat, help make nutrients available to us and neutralize toxins. Also, the microbiota play an essential role in the defense against infections by protecting the colonized surfaces from invading pathogens.
Roles in environments
The cycling of nutrients such as carbon sulfur is completed by their ceaseless labor...Decomposition is the breakdown of these organisms, and the release of nutrients back into the environment.
Reproduction
Bacteria reproduce by binary fission.The bacterium divides into two identical daughter cells.
How they work?
Bacterias breaks down sugars and toxins and it helps to protect the cells.
Diseases
Cholera, tuberculosis, anthrax.
Characteristics
They have lack of membrane-bound organelles, they are unicellular, small size.
Interesting info.
Many people think bacteria is bad, but almost all are good.
Discovered in 1674.
Bacteria has been on the planet for more than 3.5 billion years
They have a unique shape.
Virus
Roles in humans
They would drive the evolution of the cellular machinery to a greater extent than other evolutionary pressures such as predation or environmental conditions.
Roles in environments
Viruses are important microbial predators that influence global biogeochemical cycles and drive microbial evolution, although their impact is often under appreciated.
Reproduction
Our body serves the virus manufacturing thousands of new virus particles with are released to enslave more cells(thousands).
Diseases
Smallpox, common cold, types of flu, hepatitis, polio.
How they work?
They infect healthy cells and convert the not a virus. It uses its protein coat to join to the membrane of a cell. It uses complicated biological pathways force the cell to accept its genetic material or take in the entire virus itself. And finally when it is in the cell, the virus will start to use its molecular Arsenal to hijack the cells protein manufacturing systems. And when it is integrated with it, the cell will replicate its DNA and use it to manufacture proteins.
Interesting
info.
Microscopic
It has many different shapes.
They have a capsid, it is like a protein coat, and it protects de DNA or RNA genetic material.
They can't reproduce without a host.
Characteristics
They are acellular. It contains DNA or RNA but never both. They don't grow and divide.
