Annotated Bibliography

Assess sources for your research for your final presentation (for credibility, reliability, and relevance) and list references in proper APA format. That means the sources you use for this assignment should be directly related to the species that you chose in Forum 1 of the class

Assignment Instructions:  The Research Project/Presentation for this class is divided into three major Assignments, 1) annotated bibliography, 2) outline and 3) final presentation. The first part is the annotated bibliography. An annotation is a summary and evaluation, and your annotated bibliography will include a summary and evaluation of some of the sources (or references) you will use for your presentation.

To prepare for this assignment, I recommend that you do the following:

  • Read these directions carefully.
  • Review the sample annotated bibliography provided to you below.
  • Read the grading criteria below. The grading criteria is a detailed evaluation that I will use to assess your performance. It will also help you understand what is expected of you as you prepare your assignment.
  • Message me with any questions!

The reason the annotated bibliography is included as part of the research project is that writing an annotated bibliography is important in that it provides excellent preparation for the final presentation. One of the issues regarding any type of research, especially in biology, is the credibility of the sources used, particularly those obtained from various websites. By forcing you to evaluate each of your potential sources carefully, the annotated bibliography helps you determine if in fact the source you chose is credible and helps you determine how relevant it is to your topic and understand the topic better which will help you develop your presentation.

For this project, you will assess three sources to include:

1) a complete citation for each source,

2) a summary of each source, and

3) an evaluation of each source.

Three sources are required for this assignment (i.e., you are to write an annotation for each source).  However, you must use five or more sources in your final presentation. 

Use this TEMPLATE to summarize and evaluate each of your three sources.

  1. Citation:

Written in APA reference list format. For more help with formatting, see APA handout.

  1. Summary:

What is the purpose of the source, review article, original research? What topics are covered? This section is generally 4-6 sentences that summarize the author’s main point. For more help, see this link on paraphrasing sources.

  1. Evaluation:

After summarizing the article (or research paper or book), it is necessary to evaluate it and state where you found it – its source (e.g., journal, website, etc.).  Briefly answer the following questions in 4-6 sentences:

What is the format or type of source (e.g., peer-reviewed journal paper, website, book)? How reliable is the information in the article, and how credible is the source (e.g., website’s sponsoring organization, journal or book publisher) and the author(s)?

In The Plant Genus Triticum There Are Many Different Polyploid Species

In the plant genus Triticum there are many different polyploid species, as well as diploid species. Crosses were made between three different species, and hybrids were obtained. The meiotic pairing was observed in each hybrid, and this is recorded in the following table. (A bivalent is two homologous chromosomes paired at meiosis, and a univalent is an unpaired chromosome at meiosis.)

Species crossed to make hybrid
Pairing in hybrid

1. T. turdigum Ă— T. monococcum 7 bivalents + 7 univalents
2. T. aestivum Ă— T. monococcum 7 bivalents + 14 univalents
3. T. aestivum Ă— T. turdigum 14 bivalents + 7 univalents

Explain these results and, in doing so,
a) deduce the somatic chromosome number of each species used.
b) state which species are polyploid and whether they are autopolyploids or allopolyploids.
c) account for the chromosome pairing pattern in the three hybrids.In the plant genus Triticum there are many different polyploid species, as well as diploid species.

Lab 8 Identifying an Unknown Organism BIO250L” 4. What was the species of your assigned microorganism? Describe how you used your

dichotomous key to come to this conclusion. Include any relevant tests and how the

results helped you draw your conclusion.

The source of microorganism 3 is Bacillus Subtilis. I utilized my

dichotomous key and it tested positive for the starch test. The highly white

color emanating from the organism assisted in reaching this conclusion.

However, before reaching a final overall conclusion, another test must be

done hence, I examined the FTM tube and observed that the organism is an

OA organism based on the growths towards the oxygen at the top of the

tube. Lastly, due to the dark colored bacteria, the gram staining test was

positive. The other clue that led me to the conclusion about microbe 3 is

that these organisms appeared in pairs during the starch test, which is

similar to what I observed during the Gram stain. Furthermore, all

organisms are rod shaped and appear to form a chain during the gram

stain process.

Insert screenshots of your tests for your microorganism:
