Soraya's Soup Soraya left some soup in the refrigerator. She looked at the soup every day, but she always decided not to eat it. After five days, she started to see mold growing on the surface of the soup. She looked up mold online and found that mold is made of fungal cells. Why didn’t Soraya see the mold growing on the soup before the fifth day? Why can she see it now? If Soraya ate the soup on the fourth day (before she saw the mold), could she have gotten sick?
