WHAT  ARE  THE  DIFFERNCES  BETWEEN  PLANT  VIRUS  AND  ANIMAL  VIRUS?

Plant viruses infect plants. They generally have single stranded RNA. Example- Tobacco mosaic virus (TMV). 

As plant cells have tough cell wall, so plant viruses are transmitted inside plant cells through plasmodesmata. As plants are not mobile, so plant viruses always need vectors such as insects, nematodes for plant to plant transmission. These vectors also help in causing mechanical injury to tough cell wall of host plant cells, so that plant viruses get easy entry inside the plant cell.

 

Viruses that infect animals have either single or double stranded RNA or single or double stranded DNA. They cause a wide range of diseases in humans and animals. They are transmitted to hosts through various means. They can enter animal hosts through skin, gastrointestinal tract, and respiratory tract, etc. They are transmitted throughout the body through bloodstream or nervous system. Example- HIV.

Viruses are neither plants nor animals but it can infect both plants and animals. Since viruses require host cell to multiply, they can utilize the cellular machinery of both plants and animals but this does not make viruses plants or animals.

There are no such things like plant virus or animal virus. Viruses can infact  both plants nd animals. Virus that infact plants posses single stranded RNA  nd virus that infact animals r either double or single stranded RNA  or double stranded  DNA .
