    1. A web pattern is when there are hundreds of plaques on a L-agar plate, making the plate very concentrated, since almost all of the bacteria has been congested by the phage, ultimately appearing as a “web pattern”.

    1. Overall, size does not matter for bacteriophages, it only determines the morphology of the phage. For example, a phage with Myoviridae morphology will have a larger capsid head and a contractile tail, whereas if the phage had a Siphoviridae morphology will have a relatively small capsid head and a long and flexible non contractile tail. Lastly, the phage could be of Podoviridae morphology, meaning that the phage has a small capsid head and short tail.

    1. Ultimately, only the morphology of the phage would be different, as instead of appearing as a clear plaque, it would be clear in the center with a cloudy halo surrounding it.
