Question

Use a marking pen to label three plastic bags A, B, and C and put a piece of bread into each bag. Use a dropper to put 10 drops of water on the bread in each bag. Seal the bags and tape them closed with masking tape. Keep bag A in refrigerator, bag B at room temperature and bag C outside (warm place). Observe the changes for 4 days and answer the following questions. 1) How was the growth of mold different in the three bags? 2) Infer under which conditions did the mold grow best?​

Answer 1

The growth of mold was highest at room temperature.

Explanation:

1) We observe that the growth of mold was maximum in a bag which was placed in the room temperature (Bag B) and the bag which was placed outside (Bag C). This is because the fungus which causes mold grows it room temperature. I t can also grow on slightly warm temperatures. But it will take a lot of time to grow on the one places in the refrigerator.

2) The mold grew best at room temperature as all the enzymes and proteins are active at room temperature.
