The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.

Kingdoms include different phyla closely related.

The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.

All the members of the kingdom

  • Lack mobility, growing on the ground, organic matter, or other surfaces.
  • They all have a rigid cell wall composed of chitin.
  • They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.
  • Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.
  • Reproduction is by spores, which are resistant to adverse environmental conditions.
