How do I start? Observation is the key tool of a scientist. Observation helps a researcher to identify promising aspects of natural phenomena that are worth knowing about. The scientist is specifically looking for causal relationships in nature that (taken together with other knowledge) will help to explain in the broadest terms how natural systems work. The outcome of any observational process will be the formulation of one or more research questions (RQs). RQs are (at some level) guesses about the biological principles operating in a given situation. Todays exercise will be about the observation of Beta vulgaris L. , the common garden beet. It contains a reddish pigment called betacyanin. Betacyanin is found deep in the cells of the beetroot in a cellular organelle called the vacuole.
