Comparing Bacteria, Virus, Prion, and Protist

Bacteria : Bacteria are there all around us, but they are not plants nor animals. There are a few species of bacteria that are pathogenic and can cause very serious disease, but there are also many that are beneficial to human beings. There are bacteria that can provide nutrients, and the study of bacteria is known as bacteriology. Lactobacilli bacteria is one of the beneficial bacteria's due to the function of how it can aid in developing natural defenses to protect the body from dangerous diseases.

Virus : Virus is a infectious part that can replicate inside living human beings or any living organisms. Virus' can come from many animals, or from humans too. A virus can spread with blood contact, like blood-sucking insects can pass around a virus. Virus's are capable of infecting many different species all around the world.

Prion : A prion is a infectious thing that is composed of protein, it's name was derived from the words protein and infection. When a prion enters a healthy body, it immediately changes it into a sick and infectious being.

Protists : Protists have the meaning of that they are multiple cells that contain a nucleus within a membrane. Protists come from the Kingdom called Protista. Protists don't really have much in common other than their simple organization. The organization allows the protist to be known from different eukaryotes like animals or plants.
