Name some different types of cells that can occur in a refrigerator?

In a refrigerator, you can find various types of cells, including bacterial cells, which can thrive on food items; yeast cells, often found in fermented products; and mold cells, which may grow on spoiled food. These microorganisms can affect the freshness and safety of stored items.
