The sizes of Paramecium September 17‚ 2008 Wednesday Lab I am writing about the testing of sizes on Paramecium caudatum and bursaria and how they differentiate from one another. In comparing the two specimen’s size I found that the Paramecium caudatum was larger in size than the bursaria. Paramecia are unicellular organisms and are usually less than 0.25mm in length and covered with minute hair-like projections called cilia. They are characterized by their cilia which are

a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together. (Make sure you understand what a hypothesis is before you address this!) Each paramecium growing on its own will be able to grow and flourish because there is nothing stopping it or competing with it. It will be able to grow to its full capacity. When there are both parameciums growing together; one paramecium‚ the stronger of the two‚ is going to grow faster and

The article‚ Biotreatment of wastewater using aquatic invertebrates‚ Daphnia magna and Paramecium caudatum‚ mainly pertains to the idea of cleaning dirty‚ polluted water. Every since we‚ as a society‚ have switched from an agrarian to an industrial way of life‚ our waters have become increasingly polluted. Thus‚ scientists have researched conducted experiments in order to attain clean water. One of the failed attempts of attaining clean water was one in which they tried to use chemicals. Unfortunately

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

first hypothesis was to be rejected and the first null hypothesis was actually correct. The paramecium population did not fall or rise unnaturally and kept at its regular rate of increase. The second hypothesis proved to be true and that the addition of the herbicide caused the paramecium to receive it as a negative stimulus and swam away from the liquid and if a too concentrated dose was given to the paramecium the organisms died.

Paramecium movement assignment: Answer the following questions and hand in at the beginning of the next lab. 1. Describe how Paramecium moves in aquatic environments? For the paramecium to move forward‚ its cilia beat on an angle‚ backward in unison. The paramecium moves by spiraling through the water. For the paramecium to move backward‚ the cilia beat forward on an angle at the same time. If the paramecium runs into a solid object‚ the cilia changes its direction and beats forward‚ which

looked at‚ my favorite is the Paramecium. Paramecium are grouped with protists because‚ like all protists‚ they’re single celled organisms. Paramecium fall under the Protozoa Phylum in the Protist Kingdom. If an organism is in the Protozoa Phylum category‚ that means it is a small microscopic organism‚ which Paramecium are as they can only be seen under a microscope‚ and it reproduces by binary fission (splitting in half‚ becoming two new organisms)‚ which Paramecium do to reproduce and “have children”

Journal Questions 1. Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together. (Make sure you understand what a hypothesis is before you address this!) If Caudatum and Aurelia grow alone and they grow differently‚ how would they grow together? 2. Explain how you tested your hypothesis. (Give details of how you conducted your experiment. Consider this the “Methods” section of a lab report.) I first look

Paramecium is a unicellular ciliate from the kingdom Protista. Paramecium can swim in the water. However‚ when you add different chemical into water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of
