Other living organism

  1. 1. Classification of OrganismsRefer to EncartaEncyclopedia
  2. 2. Fungus- any member ofa diverse group oforganisms that—unlikeplants and animals—obtain food by absorbingnutrients from anexternal source.
  3. 3. Today thousands ofdifferent types of fungi growon and absorb food fromsubstances such as soil,wood, decaying organicmatter, or living plants andother organisms.
  4. 4. The fossil record suggests thatfungi were present 550 millionyears ago and may haveevolved even earlier. Theyrange from tiny, single-celledorganisms invisible to the nakedeye to some of the largest livingmulticellular organisms.
  5. 5. Examples:• Armillaria mushroom, a type of fungus, extends more than 12 hectares (30 acres).• Lichens, a living partnership of a fungus and an alga.
  6. 6. Algae- diverse group of simple, plantlikeorganisms. Like plants, most algaeuse the energy of sunlight to maketheir own food, a process calledphotosynthesis. However, algaelack the roots, leaves, and otherstructures typical of true plants.
  7. 7. • Algae are the most important photosynthesizing organisms on Earth. They capture more of the sun’s energy and produce more oxygen (a by product of photosynthesis) than all plants combined.
  8. 8. • Algae form the foundation of most aquatic food webs, which support an abundance of animals.• Algae vary greatly in size and grow in many diverse habitats.
  9. 9. Examples:• Microscopic algae, called phytoplankton, float or swim in lakes and oceans. Phytoplankton are so small that 1000 individuals could fit on the head of a pin.• The largest forms of algae are seaweeds that stretch 100 m (300 ft) from the ocean bottom to the water’s surface.• algae live with fungi to form lichens• Algae called zooxanthellae live inside the cells of reef-building coral.

  23. 23. • Mold and mildew are commonly used interchangeably, although mold is often applied to black, blue, green, and red fungal growths, and mildew to whitish growths.• Black bread mold, Aspergillus niger, one of the most familiar molds, begins as a microscopic, airborne spore that germinates on contact with the moist surface of non-living organic matter.

  28. 28. • The stolon is a kind of hypha connecting fruiting bodies. The stemlike part is called a sporangiophore. The roundish yellowish shapes are sporangia (plural for sporangium) the structures which bear the small round spores. Each spore that lands in a warm, dark, moist place “germinates” and form hyphae all over again.
