White molds appear in white and show flat growth. Black molds produce mycotoxins and greatly affect humans with severe health issues.
Is fungal growth the same as mold?
The main difference between mold and fungus is that mold is a multicellular, filamentous fungi whereas fungus is a unicellular or multicellular organism with a chitin cell wall. Fungi include molds, mushrooms, and yeast. A mushroom refers to a macroscopic fruiting body of basidiomycetes or ascomycetes.
How do mold spores reproduce?
Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods.

Can mold grow on paper?
There are molds that can grow on wood, paper, carpet, and foods. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or un-addressed.
How do molds get in the indoor environment and how do they grow?
Mold in the air outside can also attach itself to clothing, shoes, and pets can and be carried indoors. When mold spores drop on places where there is excessive moisture, such as where leakage may have occurred in roofs, pipes, walls, plant pots, or where there has been flooding, they will grow. Many building materials provide suitable nutrients that encourage mold to grow. Wet cellulose materials, including paper and paper products, cardboard, ceiling tiles, wood, and wood products, are particularly conducive for the growth of some molds. Other materials such as dust, paints, wallpaper, insulation materials, drywall, carpet, fabric, and upholstery, commonly support mold growth.

Why does mold need water?
Mold requires water in order to grow. Climates that have high levels of relative humidity (greater than 60 percent) have more water vapor in the atmosphere. When humid air comes into contact with structures that are colder than the air, the water vapor condenses.
What are the factors that determine the formation of mold spores?
The formation of spores is dependent on environmental factors like temperature, the presence of moisture and oxygen, as well as the availability of a food source. If these parameters aren't met, mold will not grow. 3. Spore Dispersal.
