Euglena

Euglena Experiment Biology 101         Euglena are maven-celled organisms in the division Protista kingdom. They are usually photosynthetic autotrophs but they fill the capacity 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 essay I intend to collect enough selective study to back up my hypothesis. My hypothesis is that the Euglena are attracted to distressingness.         The material that I utilize 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. low gear I prepared my microscope by placing the small clear rubbish dish full of water over the light facility in the base of the microscope to absorb heat. Next I austere two drops of Euglena in the center of the clean glass sea-coast. I consequently took a cover slip and placed iodine edge on the side of the Euglena and lowered it down well-situated like I was closing a book. I did this to ascertain trapping air bubbles. I past cut a small piece of construction paper to put about the microscope curve so that half of the square containing Euglena was in the lousiness and the other half was in the light. Then I positioned the slide so that it was in my product line of view. I used the 4x see physical object 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) Euglena were in my domain of a function of view. I repeated these steps treysome 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 some(prenominal) Euglena were in my field of view. I repeated this step three times.
