Cytokinins, gibberellins, auxins and abscisic acid, as well as polyamines, are all known to affect pollen and stamen development in a number of species e.
When sagebrush, Artemesia tridentata, a plant shown to possess methyl jasmonate in leaf surface structures, is incubated in chambers with tomato plants, proteinase inhibitor accumulation is induced in the tomato leaves, demonstrating that interplant communication can occur from leaves of one species of plant to leaves of another species to activate the expression of defensive genes.
Some sentences may contain more than one element. The turntable was rotated 90 degrees by hand. Spatial variation in seed predation is well documented e. In genetics studies include the strains or genetic stocks used. If specimens were collected for study, where and writing a science report discussion text that material was collected are stated.
By reading the title, the work being reported should be clear to the reader without having to read the paper itself. Discuss possible reasons for expected and unexpected findings.
Proper citation of references will be described later. The striking agreement between changes in microtubule orientation observed at the outer epidermal wall during tropic bending and during induction or straight growth by external auxin strongly indicates that auxin is, in fact, functionally involved in mediating asymmetric growth leading to organ curvature.
Describe the patterns, principles, relationships your results show. Do not present raw data!
Species-dependent effects of seed predation and ground cover on seedling emergence of old-field forbs. For the staining of F-actin, cells were washed and suspended in Rh-ph solution Molecular Probes, Inc. Cells at the exponential phase were spread on a MY plate and further incubated at 30oC for 4 to 6 h before harvesting for microscopy.
The duration of exposure to running water had a pronounced effect on cumulative seed germination percentages Fig. Important negative results should be reported, too. If you have performed experiments at a particular location or lab because it is the only place to do it, or one of a few, then you should note that in your methods and identify the lab or facility.
Present only the most relevant ideas and get quickly to the point of the paper. Give evidence for each conclusion. This section should not offer any reasons for those particular conclusions--these should have been presented in the Discussion section.
Authors usually write the text of the results section based upon the sequence of Tables and Figures. The plates were incubated for ten hours. Notice how the substitution in red of treatment and control identifiers clarifies the passage both in the context of the paper, and if taken out of context.
Note that superfluous detail and otherwise obvious information has been deleted while important missing information was added. Top of Page Describe your experimental design clearly. Seedlings or mature plants? The description must include both physical and biological characteristics of the site pertinant to the study aims.
It is often a good idea to include a map labeled as a Figure showing the study location in relation to some larger more recognizable geographic area. Six petri plates were prepared with agar and inoculated with the bacteria. Describe the procedures for your study in sufficient detail that other scientists could repeat your work to verify your findings.
Same actions, but all the important information is given in a single, concise sentence. The study investigated the use of the World-Wide-Web for teaching writing in a British university. Do not include any information that is not contained in the body of the paper.
Explain how your results relate to expectations and to literature cited in your Introduction. Stimulation of root elongation and curvature by calcium. Segment lengths were measured using a microscope with microgauge. Sentence structure determines the placement of the parentheses.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 summary is a brief restatement of preceding text that is intended to orient a reader who has studied the preceding text.
For a much more detailed discussion about writing scientific papers, consult: CBE. This section describes an organizational structure commonly used to report experimental research in many scientific disciplines, the IMRAD format: Introduction, Methods, Results, And Discussion.
Although the main headings are standard for many scientific fields, details may vary; check with your instructor, or, if submitting an article to a journal. Genres in academic writing: Research report discussions.
The discussion section of the report takes a broad view of the research and puts it in a wider context. The discussion section moves from the narrow specific focus of the research to a more general view.
The elements included in the discussion section text and the order in which. Formatting Science Reports. This section describes an organizational structure commonly used to report experimental research in many scientific disciplines, the IMRAD format: Introduction, Methods, Results, And Discussion.
Although the main headings are standard for many scientific fields, details may vary; check with your instructor, or, if. The Difficulties of Writing a Discussion Section.
In an ideal world, you could simply reject your null or alternative hypotheses according to the significance levels found by the statistics. That is the main point of your discussion section, but the process is usually a lot more complex than that.
The scientific format may seem confusing for the beginning science writer due to its rigid structure which is so different from writing in the humanities.
One reason for using this format is that it is a means of efficiently communicating scientific findings to the broad community of scientists in a uniform manner. report those results.Download
