Question

explain the three types of viruses depending upon the host​

Answer 1

Answer:

The virus can be classified on the basis of the type of host. They are:

1. Animal viruses

2. Plant viruses

3. Bacteriophage

1. Animal Viruses

The viruses which infect and live inside the animal cell including man are called animal viruses. Eg; influenza virus, rabies virus, mumps virus, poliovirus etc. Their genetic material is RNA or DNA.

2. Plant Viruses

The viruses that infect plants are called plant viruses. Their genetic material is RNA which remains enclosed in the protein coat. Some plant viruses are tobacco mosaic virus, potato virus, beet yellow virus and turnip yellow virus etc.

3. Bacteriophages

Viruses which infect bacterial cells are known as bacteriophage or bacteria eaters. They contain DNA as genetic material. There are many varieties of bacteriophages. Usually, each kind of bacteriophage will attack only one species or only one strain of bacteria.

Explanation:

Answer 2

In this question, we are asked to talk about the viruses depending upon the host.

• Based on the type of host, the virus can be categorized. As follows:
• 1. Animal virus
• 2. plant pathogens
• 3. Bacteriophage
• 1. Viruses in animals
• Animal viruses are those that infect and persist inside animal cells, including those seen in humans. For instance, the poliovirus, mumps virus, rabies virus, influenza virus, etc. They have DNA or RNA in their genetic makeup.
• 2. Plant Pathogens
• Plant viruses are viruses that affect plants. Their RNA genetic material is still contained within the protein covering. Tobacco mosaic virus, potato virus, beet yellow virus, turnip yellow virus, and others are examples of plant viruses.
• 3. Bacteriophages
• Bacteriophages also referred to as bacteria eaters, are viruses that attack bacterial cells. DNA serves as their genetic substance.
• Bacteriophages come in a wide range of variations. Each type of bacteriophage typically targets a single species or strain of bacteria.
