Paramecium Essays

The control experiment showed the average velocity of paramecium remain around 90.00 µms-1 throughout the 1800 seconds, due to the large groups of cilia on the surface of paramecium which beat simultaneously in a controlled, coordinated motion allowing them to maintain a steady velocity. Figure One shows that in the presence of Toxin A, Nickel, the average velocity of the paramecium begins at 80.00 µms-1, slightly lower than that of the control experiment, and decreases gradually until 1800 seconds

Wondering why animals act a certain way is possibly a question that can never be answered correctly. Asking why animals act a certain way in an environment though, now that may be a question that can be answered! It has become a proven fact that animals act differently in every different environment and around every different animal or person. For instance, take a lion that is being taken from his home environment to a zoo. Of course, that lion is going to act up before he gets used to his environment

speed of paramecium tetraurelia in different levels of treatment. Introduction Paramecia is a unicellular Protista which are naturally found in aquatic habitats. It is easily cultured in the laboratory. It is oblong shaped and covered with short hairy structure called cilia. Paramecia does not pose any health or ethical concerns and the population can be maintained if there is a food source such as Enterobacter (Biological Foundation 7). During the experiment, we observed that the Paramecium tetraurelia

The Correlation Between Paramecium and Cupric Sulfate Hypothesis: The class came to the decision to use cupric sulfate as the collaborative experiment we were about to perform. Prior, each group performed similar experiments, where each group added different chemicals to paramecium cells to see if the chemical will have any effect on their speed. After each group presented their findings, we decided to remake the experiment using the chemical group 2 used, cupric sulfate. The class came to the

seen in the experiment euglena , amoeba and paramecium unfortunately only one organism was seen and that was paramecium amoeba and euglena were not seen due to the given experiment time or due to the sample . Paramecium was seen in the light of microscope as a fast moving dot in the magnification power if 10x and then in 40x other than paramecium some other thread like structures were seen. To observe paramecium microscope coarse adjustment was used paramecium is a unicellular organism that lives in

leukocytes found in the human body. Materials/Methods: A CX31 light microscope was used to observe a collection of animal, plant, and blood cells. Both groups were also given the chance to make their own slide to look at with the Vitachrome Amoeba and Paramecium. In the second lab, students stained a blood smear slide with a Wright Stain and Buffer

How a Solute Concentration Gradient Affects Osmosis Across Semi-Permeable Membranes? By Josie Lockwood, MYP 4 Research Question: The topic that I will be investigating is: how does a solute concentration gradient affect osmosis across semi-permeable membranes? Introduction: The experiment that I will carry out is relevant as it helps us understand everyday concepts within the world: specifically, diffusion and osmosis. Before we consider the process, we must look at the history of these concepts

Maha Giundi Dr. Christos Dimos SCI4061 March 26, 2015 Lab Exercise 7: The Fungi: Molds and Yeasts Purpose: The purpose of this lab experiment is to observe examples of asexual and sexual structures of different types of fungal structures. This experiment is to also compare and contrast sexual structures of the three major fungi divisions; zygomycota, ascomycota, and basidiomycota. Hypothesis: I expect that the three sexual structures of fungi will appear to be visibly different and reflect the shapes

plants and animals. They are of following types; 1) Syngamy: The fusion of gametes takes place completely, if male and female gametes are produced by same cell or organism and both gametes fuse together to form a zygote, this is called as Autogamy, paramecium is its example. Another is Anisogamy in which some organisms produce two types of gametes. Both types of gametes differ from each other in their shape and size and are known as an isogametes or heterogametes. Male gametes are motile and small in

are responsible for nitrogen fixation. Nitrogen fixation is the conversion of Nitrogen gas from the atmosphere. This process allows the organism to synthesize nitrogen containing biomolecules like proteins. From my observations after watching the Paramecium for several minutes I came to the conclusion, that PH levels decrease causing it turn form red in color to a darker blue after digestion. The average amount of time it took to visually be able to see the entire digestion process s for a single food

As I was walking through classrooms today it became apparent, again, how well our teachers and aides provide such a wonderful education.  Mrs. Vandebossche had students looking through microscopes examining pond water to pick out paramecium and other simple life forms. They were excited to find new specimens swimming around and interacting with each other.  Mrs. Lyons was describing novels and their story lines to her students getting them excited about reading.  Mrs. Johnson, Mrs. Pfister, Mr. Wilcox

Cell Chapter Review for Test Lesson 1 LOD Cell: the smallest unit of a living thing that can carry out basic processes of life N: All living things have cells N: cells have structures called organelles LOD organelles: they work together to perform the basic processes of life N: plants and animals have different kinds of organelles to help them survive N: animals cells need to be more flexible so the animal can move around and they don’t have special organelles to produce their own food so they

In our daily lives, we are always trying to control our surroundings and what we experience. Though this can aid us in achieving our goals, our controlling behaviors can also be problematic. Rachel Carson shows us an example of this in her novel Silent Spring. Throughout her novel, she conveys how man’s efforts to control nature are mostly harmful. She exhibits this by using scientific diction, irony, ethical appeal, and imagery. Using these literary devices, Carson uncovers a usually unseen perspective

Explain what is meant by binomial nomenclature. Binomial nomenclature is a system in which every species has a two-part name. The system is based upon similarities that exist

eukaryotic  it is any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes are located. Eukaryotic cells also contain organelles, including mitochondria , a Golgi apparatus , an endoplasmic reticulum and lysosomes . example of eukaryotic cell The protists Protists are one-celled eukaryotes. However, like every rule in biology, exceptions exist. Sometimes, various seaweeds are grouped
