FUNGI

2.KINGDOM FUNGI

Fungi are plants which lack chlorophyll and live like parasite.They include, mould, yeast,
mildews mushrooms, toadstools, fuffballs, rusts, smuts and shelf fungi.

CHARACTERISTICS OFF UNGI

  • They are eukaryotic in nature.
  • They have heterotrophic nutrition as they lack chlorophyll, and they live as parasites or
  • saprophytes and digest food externally.
  • The vegetative body is known as a mycelium consisting of elongated cells known as hyphae.
  • Their cellwalls are made of chitin.
  • They store food inform of glycogen like animals.
  • They reproduce by means of spores and by budding in yeast especially.
  • They are terresterial in habitat
ECONOMIC IMPORTANCE OF FUNGI
Usefull fungi
  • Production of antibiotics like penicillin from penicillium notatum.
  • In industry yeast is used for brewing and baking and other fungi are used to flavor cheese.
  • Some of fungi are food for man e.g some muchrooms.
  • Saprophytic fungi are major decomposers in nature allowing recycling of matter.
  • In symbiotic union with algae to form lichens that are colonisers in terrestrial succession.
  • In symbiotic union with plants roots to form mycorrhiza, they increase the absorptive surface area of plants enabling it to take in more water and nutrients.
  • They are used in scientific research in genetics, cell biology and biochemistry.
Harmfulfungi
  • Parasitic fungi cause many diseases like blights, smuts and rusts in plants and candida, ringworm and athletees foot in man.
  • Causes poilage of food e.g Rhizopus which spoil bread.
  • Cause deterioration of natural materials e.g leather and wood by dry rot fungi.
