Detailed explanation-1: -With lytic phages, bacterial cells are broken open (lysed) and destroyed after immediate replication of the virion. As soon as the cell is destroyed, the phage progeny can find new hosts to infect.

Detailed explanation-2: -The host cell is destroyed in the lytic cycle. The lytic cycle is a mode of viral replication in which a virus produces many copies of itself in the host cell and those copies proceed to burst the host cell on their way out. This bursting destroys the cell and may cause some of the symptoms of the viral infection.

Detailed explanation-3: -In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host’s cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.

Detailed explanation-4: -A virus must use cell processes to replicate. The viral replication cycle can produce dramatic biochemical and structural changes in the host cell, which may cause cell damage. These changes, called cytopathic (causing cell damage) effects, can change cell functions or even destroy the cell.
