Caused by Influenza Virus
Invloves formation of cysts
In cyst form, protozoan is protected and can be spread in air and water
Not all bacteria are harmful but instead keep us healthy.
Viruses are not considered cells, and they cannot multiply without a host cell.
They are often called biological agents or particles.
Genetic Material
RNA or DNA
Prokaryotic cells do not have a nucleus, but they do have ribsosomes, a cell membrane and chromosomal DNA. Many have a cell wall, plasmid DNA, pili and flagellum.
They are single celled organisms.
"A field of biology that studies organisms that are too small to be seen with the unaided eye."
All life on earth can be classified into three groups called domains.
Archaea, Bacteria, and Eukarya. These groups can be further classified into kingdoms.
Although Viruses are not cells and are not considered micro-organisms, they are instead called particles or biological agents.
A microorganism is an organism so small that people cannot see them with the naked eye.
Microorganisms can be harmful and useful organisms.
Eukarya is one of the three groups (domains) that make up microbiology.
It can be further classified into its own kingdom, called Eukarya. The kingdom is made up of four more groups which are plants, animals, fungi, and Protista.
Eukaryotic cells do have a nucleus, as well as ribsosomes, a cell membrane and chromosomal DNA. Many have a cell wall, plasmid DNA, pili and flagellum.
They are single celled organisms.
Yeasts
Moulds
Archaea is one of the three groups (domains) that make up microbiology.
It can be further classified into its own kingdom which is simply called Archaea.
Harmful microorganisms include fungi, bacteria, protozoa, etc.
They cause several diseases in human beings, animals, and plants, which can even lead to death.
The harmful microorganisms not only can damage the human body, but also the food we eat.
What diseases can they cause?
Give examples of how the spread of harmful organisms can be prevented.
Give examples of how harmful organisms can spread.
Bacteria is one of the three groups (domains) that make up microbiology.
It can be further classified into its own kingdom which is simply called Bacteria.
Research about the main characteristics of the microorganisms and give examples!
