Prions are misfolded proteins and may form because of some misreading of the DNA code. Virions are extracellular state of a virus with nucleocapsid.
SARS (Severe Acute Respiratory Syndrome) is caused by a virus, specifically a coronavirus. It is not caused by a prion or a viroid.
A Prion. It transmits a mis-folded protein state, and replicates by causing the host's proteins to replicate into its mis-folded pattern. Mad Cow disease is an example of a prion.
The virus, prion and viroid don't meet the definition of alive which is:Movement: All living things move in some way.Respiration: Respiration is a chemical reaction that happens within cells to release energy from food.Sensitivity: The ability to detect changes in the environment.Growth: All living things grow.Reproduction: The ability to reproduce and pass genetic information onto their offspring.Excretion: Getting rid of waste.Nutrition: The intake and use of nutrients.All living things do all of these things. Viruses make use of living cells.
The viroid responsible for cucumber pale fruit viroid (CPFV) infection in cucumbers is called the cucumber pale fruit viroid (CPFV). This viroid can cause symptoms such as yellowing, stunting, and distortion of leaves in infected plants.
A prion is an infectious protein that can cause misfolding of normal proteins in the brain, leading to neurodegenerative diseases like Creutzfeldt-Jakob disease. Viroids are infectious agents made up of short, circular RNA molecules that can infect plants. A vector is an organism that can transmit a pathogen from one host to another, most commonly insects. Viruses are infectious agents that require a host cell to replicate and can cause a wide range of diseases in plants, animals, and humans.

A virus that infects plants is called is viroid.

An infectious agent consisting of a protein is a prion. This is a misfolded protein. It can cause several central nervous system diseases including Creutzfeldt-Jakob Disease, Fatal Familial Insomnia and Kuru in humans, Spongiform Encephalopathy in cows, mink, and cats plus Scrapie in sheep.A VIROID consists only of a minuscule circular RNA molecule, lacking the protein coat of a virus. Viroids appear to be transmitted mechanically from one cell to another through cellular debris. They infect only plants. Viroids are common plant pathogens which cause severe economic problems.A vector is something that carries something else. Like the bacteria on our hands or the ones on the feet of flies.A virus is much more complicated than the viroid or prion and has DNA or RNA (not both) as their genetic material with a protein coat surrounding them.
NO. It is caused by a PRION, not a virus.
No, although there is a hypothesis that prion diseases are associated with an undetected viral pathogen.
The viroid responsible for cucumber pale fruit viroid (CPFV) infection in cucumbers is called the cucumber pale fruit viroid (CPFV). This viroid can cause symptoms such as yellowing, stunting, and distortion of leaves in infected plants.
