Question

Viruses are obligated or facultative parasite​

Answer 1

Viruses are obligated parasites.

Explanation:

• Viruses are called as the Connecting link between the living and non living organisms.
• Because they are made up of only two things, that is an outer protective cover called capsid, and genetic material which may be either DNA or RNA.
• Viruses are obligate parasites because all the viruses are totally dependent on the host cell for their living, because they lack any type of cell organelles to form any metabolic functions.
• Also they depend on the host cells to perform all the vital functions of the cell including protein synthesis, energy requirement, etc.
• Whereas facultative parasites are those which generally can perform their functions themselves but they can be dependent on their host when conditions pervade.
