Today is Friday, the end of October we have 3 hour 30
minutes lecture of microbiology.we need to complete topics on protists and
algae . algae can be classified into chrysophyta, euglenophyta,
pyrrhophyta,charophyta, chlorophyta,phaeophyta and rhodophyta. In aquatic ,
algae can be found in 3 types which is planktonic, benthic, neustonic while in
terrestrial in can be found at moist rocks, trees and soil. Algal reproduction
can be divide into asexually and sexually . in asexual, there is
-fragmentation,
- spores
- binary fission.
The flagellated motile spore is zoospores and non motile
spore is aplanospores. In algal ecology provide habitat for marine community
and also human food or to make various products. Algae cause alga bloom which
high nutrition cause by dead animal,fish in the lake. Production of neurotoxin
by algae is harmful to vertebrates
Chlorophyta
Rhidophyta
Phaeophyta
Chrysophyta
Pyrrophyta
Euglenophyta
Slime molds is resemble fungi in appearance and life style .
there are 3 types in slime molds which is myxomycota,acrasiomycota and
peronosporomycetes. Function of slime molds as decomposer and consumer in
ecosystem and recycling of nutritions
In fungi, the characteristic is no cholophyll,primary
storage as glycogen and produce sexually and asexually.fungi important in
fermentation,organic acids, certain drug, antibiotics and immunosuppressive
agents.
This is structure of fungi
The three feeding form of fungi which is
Saprobic heterotrophy-eat on dead material
Parasitic heterotrophs-feed on host
Mutualistic heterotrophs-feed on host without damaging host
Asexual reproduction
Sexual reproduction
This is types of fungi
1)chytrides
2)zygote
3)sac
4)club
5)microsporidia
Next, we learn on mycorrhizae means mutualistic association
plant root and fungi. Lichen is an association of fungus and a photosynthetics
symbiont resulting in stable thallus of specific structure.lichen serve as
indicators of ecological health of an area.this is video on the fungi
