A pure culture is usually derived from a mixed culture (one containing many species) by transferring a small sample into new, sterile growth medium in such a manner as to disperse the individual cells across the medium surface or by thinning the sample manyfold before inoculating the new medium. Both methods separate the individual cells so that, when they multiply, each will form a discrete colony, which may then be used to inoculate more medium, with the assurance that only one type of organism will be present
Through chloroplasts which allow them to carry on photosynthesis and through their eyespot which allows them to find sunlight to power photosynthesis
if contamination is noted in a subculture sample, what should be to obtain a pure culture

Streak plating and picking a single colony for the culturing in a broth.
The need of pure culture of bacteria to characterize an individual species. Pure culture are also important to study the morphology and physiology of individual bacterial species, their biochemical behaviour and response to different compounds like antibiotics, which all can me alter by the influence of other species if prestent (in mixed culture) and also for isolating and studying of their molicular structure i.e. DNA or RNA. Some common ways to obtain a pure culture of bacteria are: 1 The spread plate technique. 2 The pour plate. 3 Streak plate technique.

Describe your experience interviewing individuals to obtain vital information.
The scientific method and peer review are two methods that a scientist uses to obtain empirical evidence. Experimental design and reproduction of results are two other methods.

control the contamination
Culture media should be specific to avoid contamination of unwanted microorganisms and to obtain a pure culture of microorganisms.
