  1. Explain three ways in which the growth of a typical mold is different than a typical bacterium. To help you --- think about whether bacteria and molds have a uniform cellular morphology, compare their modes of replication, suggest how bacteria and molds may have different routes for colonizing a new distant location in the environment.

A mold is a fungus that grows in the form of multicellular filaments called hyphae. Bacteria are genrally smaller and more numerous in size.

Molds can grow on any substance when moisture is present.They reproduce by spores, and when thespores are dispersed by air currents and land on moist surface suitable for life, they begin to grow.

bacterial growth can be described as elevation:

  • raised in a shallow dome shape
  • raised in a steep dome shape
  • flat growth parallel to the surface
  • umbonate growth with a raised bump in the centre
  • craterifrom growth with a concave dip in the centre

bacteria replicates by binary fission,whereas yeasts reproduce by budding. Unlike bacteria, moldsare made of more than one type of cell. Vegetative cells intake food for enegy and the reproductive cells produce spores

Colonosation is the presence of bacteria on and around the surface and that doesnt produce any symptoms,yet spread microorganisms in the environment. Bacteria that live in the environment establish attachment with the solid surfaces by hydrophobic interactions and may form biofilms.

Fungal colonisationis identified by the presence of vegetative growth represented by ramifying hyphae. The colonisation may be temporal and microscopic, or extensive and obvious by sight and smell in the buildings with moisture problems.
