differed between my group’s nutrient agar and MAC agar plates. In courgette‚ there was moderate growth in nutrient agar while it was heavy in Mac agar. In beef broth‚ there was slight growth in nutrient agar while it was negative in MAC agar. In fresh basil‚ growth was heavy in nutrient agar while it was heavy in MAC agar. Where cottage cheese was the ingredient‚ both plates had heavy growth. For walnut‚ growth was slight in nutrient agar while it was negative in MAC agar. Generally‚ the slight difference

Diffusion in agar cubes Introduction: All cells are dependent on a processes called diffusion‚ which is the movement of a substance from an area of higher concentration to an area of lower concentration. Cells need to obtain certain essential substances‚ like oxygen‚ for their survival. The rate of diffusion is said to be dependent upon the various factors: Size of molecules that have to diffuse‚ concentration gradient‚ the distance across which diffusion occurs‚ number of pores/openings‚ surface

growth of bacteria on Agar plates Hypothesis: That the bacteria will grow in colonies throughout the agar plates except for the one with the anti-biotic loop because some will fight off the bacteria. Method: (Method taken from prac sheet) Plate 1: Use the swab to cover your entire agar plate in your bacteria. You only need one swab of bacteria but be careful to cover the entire surface of your agar in a layer of bacteria. Carefully place an Antibiotic Mastring on top of the agar (use tweezers) in the
