After creating our Hay Infusion culture on Tuesday, we reexamined it in lab on Thursday. During this short period of time, a significant amount life was able to be supported. To find out more about what exactly was growing in our culture, we took samples from different parts of the jar and examined them under the microscope. Some of the organisms identified were colpidium, paramecium and gonium. Paramecium move using cilia. They do not photosynthesize and have 2 nuclei. They produce both asexually by binary fission or sexually through conjugation which exchanges micronuclei.
It was difficult to take a good picture through the microscope, but the photo below is an example of what one sample looked like under the microscope.
If the Hay Infusion Culture was observed for another two months, an increase in the number of protists and development of a more complex ecosystem would likely be observed.
