How does fungus grow on food?

Answer 1

Spores are like eggs that has not been fertilized yet. When spores (which are all over the place) land on food, and the conditions are good (moist, food, oxygen, dark, etc), they produce microscopic filaments called hyphae (fuzzy stuff you see on food). They secrete enzymes to digest the food that they are growing on, and absorb the digested food. If they are growing well, some of these hyphe come together and fuse, resulting in fertilization. Out of that grows a stalk with sporangia (look like tiny little balls), which make more spores.

Answer 2

Fungi usually reproduce by spores. If a fungus is growing on food, then it means the food has been exposed to spores of some kind.

Answer 3

Spores from mold and yeasts are all over in the environment. They are on the out side of the fruit. When they get inside they eat the fruit and you see it as rot and brown and liquid. Some times you can take it off other times it goes all the way through and you need to throw out the fruit.

Answer 4

Spores are practically ubiquitous.
If they land on an appropriate culture medium (food) under the appropriate conditions of heat, humidity, light, the fungal spores are likely to activate and become mature fungi.
