Read this essay on osmosis come browse our large digital warehouse of free sample essays the test showed that s epidermidis and s cerevisiae can grow in concentrations of nacl because both have adapted to the effects of nacl in response to the osmotic pressure. Lab 1: introduction to the microscope and comparison of sizes and shapes of microorganisms this yeasts, such as the common baker's yeast saccharomyces cerevisiae (see fig 4), are unicellular fungi. Todar's online textbook of bacteriology discusses the techniques, media and environmental conditions for growing bacteria.
