Yeast Experiment

Title The shape of barm cell per ?cm?^3 over the range of dilution of yeast gap Aim To see the number of yeast cells per ?cm?^3 in different dilutions of yeast breaking. Researched Question Does different dilutions of yeast suspension effect the number of yeast cells per ?cm?^3 Hypothesis As the dilution of the yeast suspension increases, the number of yeast cells per ?cm?^3 decreases. This is because when 1 ml of yeast suspension is diluted into 9 ml of distilled water, and the mixture is stirred equally, the yeast cells will be scattered equally in the ladder tubing. The ratio of the yeast cells to the volume of the distilled water. Therefore, when the number of yeast cells per ?cm?^3 is taken, the number of yeast cell per ?cm?^3 will decreases in any dilutions. Variables Manipulated variables Dilution of yeast suspension which are ?10?^(-2), ?10?^(-3) ,??10?^(-3) ,10?^(-4) ,?10?^(-5) ,?10?^(-6) ,?10?^(-2) Responding variables Number of yeast cells per ?cm?^3 Controlled variables script of distilled water 9 ml of distilled water are poured into the streamlet tube to be free with 1 ml of the yeast suspension.

Type of specimen use The yeast cells are used in this experimentationation Volume of suspension of yeast cells For both dilution, 1 ml of suspension of yeast cells is poured into the test tube to be dissolved with 9 ml of distilled water. The enlargement used The magnification for every experiment is 10x objective of the microscope.
