Scientists classify plants and animals on the basis of tasonomy. Taxonomy is classsification, identification and nomenclature of living organisms. Taxonomy is used to classify organisms on the basis of their characteristics, mode of nutrition etc.
scientists use taxonomy to classify and separate them into different groups
because structural characteristic do not change over time but physical appearance do
Binomial Nomenclature.
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
