NEET BIOLOGY

Detailed explanation-1: -Virus-a small nonliving particle that invades and then multiplies inside a living cell. Biologists consider viruses to be nonliving because viruses are not cells. Viruses do not use energy to grow or respond to their surroundings.

Detailed explanation-2: -virus: Tiny, nonliving particle that contains DNA (or RNA) surrounded by a protein coat; lacks other characteristics of living cells.

Detailed explanation-3: -A virus is a tiny, infectious particle that can reproduce only by infecting a host cell. Viruses “commandeer” the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory. Because they can’t reproduce by themselves (without a host), viruses are not considered living.

Detailed explanation-4: -Viruses are considered as something between living and non-living because they do not grow or reproduce by themselves. This makes them non-living. However, when a virus enters a living cell of an organism, it obtains energy from the host cell and starts reproducing.

Detailed explanation-5: -The virus has living characteristics like, they don’t have a cell, the virus can be crystallized and stored for long days, the virus is inert outside the host and the virus don’t have any cell organelle and unable to metabolize.
