Results: Interpret the naked data from the previous section to explain the sense of the experiment to the target audience. If it were not for people looking for the new and unexpected, nothing would ever be discovered! Materials and Methods takes the reader step by step through the laboratory procedure that the experimenters followed. Since an abstract is so short, each section is usually only one or two sentences long. That is, were the effects on reproduction, survival, dry weight or something else? One important general rule to keep in mind is that a scientific paper is a report about something that has been done in the past. A major goal of plant ecology is to explain spatial variation in a species frequency of occurrence. Male sterility in plants is generally associated with the lack of production of viable pollen; however its expression can vary Frankel and Galun , Kaul For additional instruction on writing in biology, see John Bishop's page.

The failure or inability of an individual to produce functional gametes under a given set of environmental conditions is known as sterility. Generally speaking, the Results begins with a succinct statement a sentence or two summarizing the overall findings of the experiment.

In writing the Materials and Methods , Results , and Discussion sections, you have outlined the issues that your report discusses. Do not repeat extensively in the text the data you have presented in tables and figures. Then inoculate the plates with the bacteria. Salt Tolerance in Phaseolus vulgaris.

Listed below are several examples of how citations should be presented in the text of your paper.
In this experimentreferred to as the variable pH experiment, we examined the rate of reaction of catechol and oxygen again, but this time when the pH was varied. Sample 2: It is well known that enzymes are catalytic proteins which function to accelerate reactions by lowering the activation energy Campbell, The Discussion section often begins by making a statement as to whether the findings in the Results support or do not support the expected findings stated in the hypothesis.
Any terms that are used within the report that are necessary for understanding the report should be defined within the introduction. The text describes the data presented in the tables and figures and calls attention to the important data that the researcher will discuss in the Discussion section and will use to support Conclusions.
