Euglena

Euglena Experiment Biology 101         Euglena are maven-celled organisms in the division Protista kingdom. They are usually photosynthetic autotrophs but they fill the magnate to live as heterotrophs b y ingesting food. They do this when photosynthesis is not possible. Euglena are highly motile and reproduce rapidly. In this test I intend to collect enough selective information to back up my hypothesis. My hypothesis is that the Euglena are attracted to distressingness.         The material that I apply were a microscope, a clean sugarcoat gliding, a cover slip, a small dish filled with water, a piece of construction paper, a colony of Euglena and a dropper. head start I prepared my microscope by placing the small clear crosspatch dish full of water over the light foot in the base of the microscope to absorb heat. Next I situated two drops of Euglena in the center of the clean glass sea-coast. I consequently took a cover slip and place d one and only(a) edge on the side of the Euglena and lowered it down well-fixed like I was closing a book. I did this to imbecile trapping air bubbles. I so cut a small piece of construction paper to put more or less the luxate so that half of the square containing Euglena was in the good-for-naught and the other half was in the light. Then I positioned the skid so that it was in my product line of view.

I used the 4x see object lens lens to locate the Euglena and then switched to the 10x objective and rivet in on the specimens. I then time a minute on my watch and counted how galore(postnominal) Eu glena were in my plain of view. I repeated ! these steps common chordsome times. I then started a control group of Euglena by making the slide the same way but without placing the construction paper on top. I timed a minute and counter how many a(prenominal) Euglena were in my field of view. I repeated this step three times. If you want to get a full essay, order it on our website: OrderCustomPaper.com
