Algae And Fungi



              4 hours of lecture. YESSSSSSSSSS. We covered about algae and fungi. But before that, Dr Wan talked  a bit about our THANK A  MICROBE project. The winner is GROUP 2. And I do agree with it because one of the group members, Chew, explained everything in detail. So yes. They deserve it. Yeay congrats!


           Okay then we back to our lecture on algae. Actually we had covered this topic before. So I think I will not emphasize about it in this post as I have done it in previous post. But I want to talk a bit about algal bloom. It is actually caused by high nutrition in lake or pond. The high nutrition is due to a lot of dead plants and animals suspended in the lake or pond.  And where chemical changes occur, toxic gases will be releases. The production of toxin kills marine organisms such as small fishes. However it does not kill big fishes. In fact, big fishes eat those algae in order to clean the lake or pond back. If human consume that particular big fishes, then it will be harmful to human. There is also red tides which caused by dinoflagellates that produces brevetoxins. These brevetoxins could result in respiratory irritation in human.

   For fungi, there are 4 types of fungi which are, chytrids (Chytridiomycota), zygote (Zygomycota), sac (Ascomycetes) and club (Basidiomycetes). There are few things that I actually think it is important to know,

  • Fungi are classified and identified by spore type 
  • Fungus spore and bacterial spore are different 
  • Sexual and asexual reproduction occurs by formation of spores 
  • Fungi act as decomposers ( recycling carbon, nitrogen and other elements to the ecosystem) 
  •  Fungi modify habitat (lichen inhabit inhospitable places and make habitat suitable for life 
  • Fungi act as spoilers decompose food/wood 
  • Fungi improve plant growth 
  • Fungi as food for animals and humans 
  • Fungi as pathogens (it causes athletes foot, ringworm and yeast infection)
