Micro-Organisms Week 1

Observing my Micro Aquarium for the first time out of lab some of the Micro-Organisms I found were named. After I got my Micro Aquarium out of the specific container it was in I then went over and placed it under the microscope. Dr. McFarland came over to me and begin naming some organisms and showed pictures in the book titled Free Living Freshwater Protozoa A Colour Guide by D.J. Patterson.

Organism 1: The first organism Dr. McFarland identified was called Anisonema sp. Anisonema sp. has two prominent flagella that are unequal in breadth and length The anterior flagellum is the weaker of the two, beating normally. The recurrent flagellum is much broader and trails along the ground as the cell moves (Patterson,1992,figure 78,p.77). It was interesting to look at because of the way flagellum worked and how the organism moved.

Organism 2: The next thing Dr. McFarland helped identify was called Tachysoma sp. Tachysoma sp. has well developed (immotile) dorsal bristles which can be confused with cirri. The adoral zone of membranelles has the typical coolar-and-lapel arrangement  (Patterson,1992,Figure 265,pg.125).
