Because microorganisms donot have enzyme to break down plastics molecules.
they need air,food,water and warmth to grow.if you put the bread in a plastic bag and put it in the warmth place,the fungi will grow.
hihiWith a more serious answer , you can grow fungi out of bread by sealing a piece of bread in a plastic bag and taping it to your window. Soon you will see condensation form on the plastic as moisture gathers in the bread. You'll start seeing fungi sometime after that, around the decomposing stage I assume.
a plant can kinda grow in a bag but it also can not grow a lot but only a little
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.
It will mold!
Not if it is an artificial sponge.
To effectively grow seeds in a plastic bag, you can follow these steps: Moisten a paper towel or cotton pad and place it inside the plastic bag. Place the seeds on the moistened paper towel or cotton pad. Seal the plastic bag and place it in a warm, sunny location. Check the moisture level regularly and add water if needed. Once the seeds sprout, transplant them into soil to continue growing.
in the plastic bag first

fungi and bacteria grow from spores.
There is typically only one plastic bag inside another plastic bag, unless they are packaged in multiples.
Mold can grow in a sealed plastic bag because mold spores are present in the air and can easily enter the bag through small openings or microscopic imperfections in the plastic. Once inside, mold spores can thrive in the warm, moist environment created by trapped air and any residual moisture in the bag. The lack of airflow and sunlight in a sealed plastic bag also creates ideal conditions for mold growth, as mold thrives in dark, damp environments.
