They are motile like animals but some are unicellular so they cannot be classified as animals. There are several types of Slime Molds. Plasmodial slime molds (such as Physarum polycephalum) are slime molds that form giant, multinucleated cell colonies. ... Cellular slime molds remain as unicellular 'slug-like ' amoeboid protists for much of their life, crawling through leaf matter and

    QUESTION: Our question was “What effect does the size of container have on the population of protozoans? BACKGROUND: We had three jars; one control which was the size of the ones we initially used, one that was half that size, and one that was three times that size. They both had 1.2 grams of grass to 50 milliliters of water. We covered the jars starting on the second day. The experiment went on for 26 days, and we fully observed on 3 days. To try to make the test fair, we tried to do what made

    of life in the world: Bacteria, Archaea, and Eukarya. Bacteria and Archaea are both prokaryotes. Prokaryotes are single cell organisms that lack a nucleus in the membrane nor other specialized organelles. For Eukarya it consists of four kingdoms: Protists, Plants, Fungi, and Animalia. The domain consists of organisms with a cell nucleus and other organelles inside a membrane. With these seven kingdoms scientists have been able to edge closer to classifying all organisms in the world, and are exploring

  • Acid Phosphatase Lab Report

    1870 Words  | 8 Pages

    Acid phosphatase is an enzyme commonly found in nature in plants, animals, and protists. Acid phosphatase is found in human bone and prostate tissue. The optimal conditions of acid phosphatase were tested using Michaelis-Menten kinetics to determine the ideal substrate concentration, varied pHs were tested in order to determine the optimal pH, and various temperatures were tested in order to determine the optimal temperature. Using Michaelis-Menten kinetics, the Vmax was determined to be 312.5 nmol/min/mg

    The text starts out describing the earth’s biosphere as a membrane that stretches from the ends of the earth, encapsulating everything in a layer of life. Edward O. Wilson continues the first chapter by describing some of the most extreme climates of the earth; as well as the microscopic organisms that manage to withstand these conditions. One example being the harsh climate of the McMurdo Dry Valleys of Antarctica, where freezing temperatures prevent the soil from being warm, rich and nutrient-bearing

  • Difference Between Prokaryotes And Eukaryotes

    Gerald McDonnell 1. The major differences between prokaryotes and eukaryotes are as follows; prokaryotes are much smaller than eukaryotes, prokaryotes have a nucleoid instead of a nucleus (which eukaryotic cells have), prokaryotes lack a membrane bound organelles while eukaryotes have them, prokaryotes are bacterial cells while eukaryotes can be considered the building blocks of plant and animal life. 2. A. A nucleus is basically the “brain” of a cell. It controls reproduction and contains the genetic

    make up all living organisms. Humans are made up of over a trillion cells; red blood cells, white blood cells, skin cells, and more, are all a part of what composes the human body. But, cells also make up the body and structure of bacteria, archaea, protists, fungi, plants, and animals. They can be comprised into two different categories: the eukaryotic cells and the prokaryotic cells. Eukaryotic cells have membrane-bound organelles and a membrane-bound nucleus, while prokaryotic cells have no membrane-bound
