Yeast Cells and Haemocytometer

SITI MARDHIAH BINTI MUHAMAD FAUZI (M12B)31ST JULY 2012 TITLE : YEAST CELLS AND HAEMOCYTOMETER Research Question: How does the contrasting dilutions of barm geological fault affect the tot up of barm cells in atomic number 53 cm3 of the dilutions? Hypothesis: The higher the dilution office of the yeast foramen, the little the number of yeast cells in peerless unproblematic square. This is because when dilution factor of yeast suspension increases, more pee is added into the solution making the yeast cells in the yeast suspension more widely distributed, hence leading to the concentration of yeast cells in one primary square (0.1 mm3) to decrease.
