Question
Chapter 27, Problem 14PIAT
Summary Introduction
To review:
The experiment that will test whether the coating of extracellular slime will change the speed of the organism across the substrate or not.
Introduction:
To test the change in speed of slime mold across the substrate can be detected by using different substrates. The growth substrate that can be used is plain agar and the precoated agar with the extracellular matrix.

- This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Different cells and culture media absorb best at a specific, known, wavelength. In this case the amount of light transmission is related to the number of bacteria present. Optical Density is the value given to the measurement of turbidity. Environmental factors, such as temperature and pH, can disrupt the structure of enzymes, resulting in denaturation and making them unable to function.The growth of microorganisms can be controlled in the laboratory by altering environmental factors, such as temperature, oxygen content, osmotic pressure, and pH. write in your own words the Microbial Growth - Effects of pHarrow_forwardIf I placed pieces of beetroot in a test tube and the test tube was placed in hot water, making the test tube water pink, how could i provide evidence on why the membrane is semi permeable?arrow_forwardExplain why a jar of jelly can be left open on the kitchen counter for prolonged periods of time, yet no mold or bacteria will grow on it?arrow_forward

Both stained and living representatives will be examined. They exhibit diverse characteristics morphologically and nutritionally. Considerable variations can be found in their shape, cellular structure, types of motility and size. They can be autotrophic and heterotrophic; chlorophyll-free and chlorophyll containing; unicellular and multicellular; saprophytic and parasitic; and ranging from bacteria to algae, fungi and protozoa. Some concepts of diversity of morphological types among organisms can be gained by careful microscopic examination of such specimen.arrow_forwardThe graph shows the number of microbial cells (log scale) against time in a liquid culture.
