As we know, a virus may be classified as a nucleoprotein entity since it can replicate itself by utilizing the synthetic machinery of an existing cell of another creature.
When we talk about a parasitic creature, we may state that it cannot complete its life cycle in the absence of an adequate host, which is known as an obligatory parasite or holoparasite.
As a result, we may assume that if an obligatory parasite cannot find a suitable host, it will fail to reproduce.
They are unable to proceed without the assistance of a live organism
We can see that virus cells cannot develop in a non-living culture medium.
It needs live cells mostly for metabolism and growth.
As we know, virus cells replicate by autonomously establishing their components using host machinery and then assembling their parts to form viral subdivisions.
Finally, we may conclude that the virus lacks prickliness and motility. .
