They are obligate paracites.They cannot multiply without another living cell
viruses are considered parasites (obligate parasites) because they cannot exist on their own. they need the host cell's machinery to reproduce so they cannot "survive" (technically not living) outside the cell.
Parasites can carry and transmit viruses, but they do not "cause" them.
because none of them is capable of replicating itself outside the host
Viruses
No; viruses are sub-Cellular 'virons', while parasites are frequently multi-cellular organisms.
parasitic mode of nutrition
bacteria, viruses, fungi and parasites
Because viruses can not reproduce or produce protein without a host cell
Yes because all the viruses uses host cell mechanisms to reproduce and then at the end of the reproduction process it destroy the host cell.Therefore there is no non-parasitic viruses.All viruses are parasitic.
They both destroy the cells that they attack.
Immunity
Viruses are often referred to as parasites because they depend entirely on a host cell to replicate and carry out their life processes, similar to how parasites rely on a host for survival and reproduction. Unlike living organisms, viruses lack the cellular machinery and metabolic functions necessary for independent life, making them obligate parasites. They invade host cells, hijacking their machinery to produce new viral particles, which can lead to disease in the host. This parasitic behavior underscores their reliance on living organisms for their existence.
