  • Morphological characteristics:-
    In other hand molds are beneficial in preparation of some food like cheese and a few Oriental food.
  • Molds are certain multicellular filamentous fungi whose growth will be easily recognised by its cottony appearance.
  • Morphology means form and structure of mold is set by a microscope. its accommodate of a mass of filaments called as hyphae and a mass of this hyphae is known as mycelium.
