Why are petri dishes sealed with sticky tape?

Petri dishes are sealed with sticky tape to prevent contamination from airborne microorganisms and to maintain a controlled environment for the growth of cultures. This sealing helps to minimize evaporation of the culture medium and reduces the risk of spills or exposure to external contaminants. Additionally, sealing can help maintain humidity levels, which is crucial for certain types of microbial growth. However, it is important to allow for some air exchange to prevent the buildup of gases produced by growing organisms.
