The Amoeba
Introduction
Amoebas are little one-celled microbes classified as protist that live in ponds, lakes, streams, and puddles. They move by extending their body into false legs which are called pseudopods. Their pseudopods also form to engulf prey as food particles. Amoeba are mostly like a jelly substance but enclosed in this jellyform which is made of cytoplasm where you will find a nucleus, a food vacuole, and contractile vacuole. Amoeba breaths in oxygen from the water and extract carbon dioxide. The team will observe how the amoeba looks and moves and hopefully can witness one engulfing food.
Materials and Method
The team obtained a sample of pond water and applied to a slide for observation under the microscope as we did with Euglena and Paramecium. With extensive looking the team did not find any amoeba protist from the sample pond water collected.
Results
We did observe the amoeba from a classmate's microscope which was as a blob of clear jelly substance. We could not see it moving but as you can see from the attached video, you will see the slow movement of their pseudopods as they extend out to move.
Discussion
Amoeba are not just blob of jelly. Some amoebas have filose pseudopia such as the genus Penardia mutabilis species.
