PRESENTATION OUTLINE
Protista: Eukaryotic unicellular organism
"True protozoans"
Single-celled microscopic animals (ameba, flagellate, ciliate, and sporozoan)
3. ROTIFER & 4. COLPIDIUM
MAGNIFICATION OF THE ORGANISMS (OSCULAR LENS)
1. In the given sample, there were mainly phylum (ciliates) and multicellular organisms
2. Partial reason of why it was hard to find and identify the actual Protista is because there hasn't been a chance to get familiar with using microscope and applying the lesson through the given samples at all. But still, what really caused this problem was the lack of knowledge students had since they (us) are just started to learn both using the microscope and different types of Protista.
3. The most interesting organism from the pictures taken (by me) was actually rotifer. At the first glance, rotifers seemed to have what reminded of the circular chain saw sucking on very small particles from the pond water sample.
4. Planarian was a elongated organism that moved using the very thin flagella (probably). If not, it must be moving using slimes to slide upon or using unseen cilia to propel itself (cilia would be the next shot).
5. Colpidium is an unicellular organism living in moist soil or the edge of the water (in this case, pond). It feeds on a wide variety of bacteria and is eaten by many kinds of copepod. Colpidium affects the food web (as it has been talked about above) for the matter of biotic factor, and colpidium can also be used to assess the toxicity of soil as mean to detect chemical contamination (possibly for terrorist attacks) - this can be the abiotic factor. In pond, colpidium can be in use of knowing if the pond is toxicated or not.
