CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Due to their simple structure, viruses cannot move or even reproduce without the help of an unwitting host cell. But when it finds a host, a virus can multiply and spread rapidly.

Detailed explanation-2: -A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself. Often, a virus ends up killing the host cell in the process, causing damage to the host organism.

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 cannot reproduce outside the host because these organisms do not have the metabolic machinery of their own. Viruses do not have cytoplasm and enzymes required for reproduction. In this regard viruses must approach their respective host for reproductive components.

Detailed explanation-5: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.
