Mold grows really well on both damp bread inside a sealed plastic bag, and any type of meat.
It will mold!
The quickest way to grow mold on bread is to expose it to warm and humid conditions, such as placing it in a sealed plastic bag or container at room temperature. Adding a small amount of water can also accelerate mold growth on bread.
Mould will grow faster in a plastic bag if it's not kept refrigerated. If it's left in a paper bag, it will firstly go crusty, then mouldy but the plastic bag option will make it go mouldy faster because of the condensation which is produced. I work in a bakery.
plastic
If you wet raspberries then put them in a plastic bag in a dark area such as a cabinet or pantry mold will start to grow within the first 48 hours
Mold grows faster on a counter compared to in a sealed bag because mold requires oxygen, moisture, and a food source to thrive. A bag restricts airflow and moisture, slowing down mold growth compared to a moist and exposed counter surface.

In an airtight plastic bag that is sealed
Grab your piece of food (Bread works too, which I would say is better to experiment mold with) and place it in a zip lock plastic bag or one of those that clip closed at the top. Seal the plastic and leave it somewhere out of harm's way. After a day or two you will notice that the fruit will start getting wrinkly and black (Or green from the mold Tricholoma on breads) and it will eventually become a black lump day by day. NEVER OPEN THE BAG UP ONCE THE MOLD HAS STARTED. After a week of first spotting the mold, dispose of the plastic bag with the fruit or bread STILL SEALED INSIDE carefully.
Bread can become mouldy in a sealed plastic bag due to high humidity levels, allowing moisture to accumulate inside the bag and create a suitable environment for mold growth. Additionally, if the bread was not completely cooled before being placed in the bag, condensation can form inside the bag and contribute to mold growth. Proper ventilation and storage in a dry environment can help prevent bread from becoming mouldy.
Mold is likely to grow faster on an apple in a bag because the high humidity and limited air circulation provide an ideal environment for mold spores to thrive. The enclosed space in a bag also traps moisture, promoting mold growth.
