Question

what will happen if you keep a piece of moist bread in a corner of a room for some days

Answer 1

There will be much holes seen in the bread because if it is kept there the bacterias such as yeast try to eat the bread and make it soft.

Answer 2

If we keep a piece of moist bread in a corner of a room for some days, we will notice mold growing on it.

Mold is a type of yeast that grows by extending multicellular filaments known as hyphae.

Since mold grows best in dark,warm and moist conditions,the bread in the corner of the room provides the best condition for the mold(yeast) to grow.
