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.
This is the picture
of my marks for crossword activity. (I used hint few times, that is why
hahahaha).
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)
