5. If colonies appear within a plaque or the plaque is cloudy, what is the most likely reason?
Reason : A mixture of lysed cells (due to lytic infection) and lysogenized cells (due to a lysogenic cycle) are turbid plaques. The plaques appear turbid (cloudy), because inside the plaque the lysogenized cells live and form small colonies.
Clear plaque: no growth
Turbid plaque: some growth (colonies)
No growth with transparent plaques, as white plaques only contain phage. Some development of turbid plaques, as the lysogenized cells are going to survive and colonize.
