Openstax Microbiology Ch. 9 |Questions and Answers(A+ Solution guide)

binary fission - ("division in half") is a kind of asexual reproduction. It is the most common form of reproduction in prokaryotes and occurs in some single-celled eukaryotes. The fully grown parent cell splits into two halves, producing two new cells. Generation time - is the time it takes for a cell to divide colony (CFU) - Colony Forming Unit, Growth is exponential and results in an isolated of cells Direct Count - counts bacteria using a specially made slide, the slide has a grid and for each bacteria in the grid that's how you count. Serial dilution - _______________ involves diluting a fixed volume of cells mixed with dilution solution using the previous dilution as an inoculum. The result is dilution of the original culture by an exponentially growing factor. 2 Bacteria makes a... - colony Plate dilution - uses warmed agar to dilute rather than diluting solution Drinking Water - Very dilute samples such as ______________ use filtration to count bacterial cells. A known volume of water is filtered through a membrane that traps the bacteria. The filter is then laid on agar to grow. Use the CFU number to extrapolate the number of bacteria in the original volume of water. Turbidity - The cloudiness of the growth of the bacteria Biofilms - A group of bacteria that will stick to an inert (nonliving) surface in the body; highly structured ecosystem of numerous species of microbes growing on a surface.
