Kingdom Fungi

• Includes mushrooms, moulds and yeasts
• They do not have stems, roots or leaves
• They are made up of many thin threads called
  hyphae (long filament-like, or thread-like,
  strands of cells). Enzymes are secreted by the
  hyphae to digest food. The digested food
  particles are then absorbed through the surface
  of the hyphae

Kingdom Fungi

• They have a cell wall, a nucleus and other
  organelles
• They do not have chlorophyll so they cannot make
  their own food by photosynthesis
• Some feed on dead organisms or non-living organic
  matters (saprophytic)
• Some are parasites in plants and animals, and
  cause diseases, e.g. athletes foot in human
  (parasitic)

Kingdom Fungi

• Fungi reproduce by spore formation
• Spores are extremely tolerant to unfavorable
  conditions and can be carried by wind to far
  away places
• When spores land on a suitable medium under
  suitable conditions, they can geminate into new
  fungus-forming hyphae

Mushrooms

• Usually found on dead organic matters

9
Moulds

• Commonly found on stale bread, cheese or fruits

  where sugars are present, such as fruits and
  flowers
