Final answer:
A webbed plate refers to interconnected colonies on a bacterial culture plate, while a completely cleared plate has no visible colonies. The former indicates bacterial growth, while the latter signifies no growth. The presence of mold can result in webbed growth on the plate.
Step-by-step explanation:
A webbed plate refers to a bacterial culture plate where the growth forms interconnected colonies. These colonies can spread across the entire plate, creating a network-like appearance. On the other hand, a completely cleared plate refers to a plate where there is no bacterial growth and the agar surface is transparent without any visible colonies.
The difference between the two plates is that a webbed plate indicates the presence of bacterial growth and the formation of a network of interconnected colonies, while a completely cleared plate suggests that there is no bacterial growth or any visible colonies on the plate.
