ORGANELLE FUNCTIONS—JOB DESCRIPTION and HELP WANTED ADVERTISEMENTConduct web research to determine the function of cellular components. Write "job descriptions" for each of the organelles found in a plant or an animal cell. What you will doConduct web research to determine the function of cell organelles Review examples of job descriptions Demonstrate understanding of organelle function What you will needOrganelle Functions Handout (below)Web Sites:Organelle functions:MIT's Biology Hypertextbook (Select Cell Biology)Cells Alive!Virtual CellSample job descriptions:Writing Effective Job DescriptionsCareerZoneThe steps to followResearch either plant or animal plete the research and written assignment, as outlined on the Organelle Functions Handout (below).If you need additional examples of written job descriptions, a web search for "job description format," using a search engine such as Google or , yields numerous sites. As job description postings can be rather transient, specific examples are not listed here.Submit your completed job descriptions to your teacher for assessment.Be prepared to discuss the role of each organelle in cellular function, the differences between the structures of plant and animal cells, and the variations in prokaryotic and eukaryotic cells.

The employees of a factory work to create specific products and maintain the factory's viability, just as the organelles of a cell work to meet its varied needs. Biochemical, growth, and reproductive functions must be fulfilled if the cells, and the organism as a whole, are to survive.In the workplace, the responsibilities and roles of each employee are specified in a formal document, called a job description.In this project, you will use the information that you collect to write job descriptions regarding the functions of a cell's organelles as well as a help wanted advertisement.Using the provided web sites, identify and determine the functions of the organelles that are found in the cell type you are researching. Be sure to collect all of the information needed to write a job description for the organelle, as outlined in the next step. Write a job description for each organelle, using the following format: Name of Company:Choose a name that reflects the functions of cells. Be creative!Job Title: Name of the organelle and/or a title that reflects its roleDepartment:What role does the organelle act to fulfill? Division:What role does the department, as a whole, act to fulfill? Scope:An overview of the job responsibilitiesMajor Responsibilities:Key tasks to be performed Position in Organization:To whom does the organelle report? Who reports to, and is supervised by, the organelle?Relationships:internalexternalAre there other organelles, within the cell, to which this one relates?Are there other cells, specific tissues, organs, etc., with which this organelle interacts?Expected Outcomes:What are the main products that this organelle makes and/or what functions does it serve?Organelle Functions Handout Continued… After you have completed the “job description” for your organelle, you will need to create a Help Wanted Ad. Here is a sample want ad that I found online; it is adapted from the work of a student in South Lake, TX. Can you guess the organelle? “Looking for a great opportunity to lead? Do you enjoy making decisions for others? Is guidance your strong point? If so, we are seeking to fill a managerial position. We are in need of a control center for a cell. Must be able to operate a cell. Should have solid experience reading and de-coding DNA. Should exhibit strong leadership skills. Benefits include: placement in low-stress arm cells, long life guaranteed...you don't die; you just divide and multiply! If interested contact The Body at 817-8WE-CELL.” Your want ad should be created with a 2.5 in wide space for the text. Change your margins or create a text box for your ad. We will try to piece our ads together to make a "page from the newspaper" to post in the room. Do not include the name of your organelle in the ad so other students can try to figure out which one it is. **If you use additional websites than the ones listed above, you MUST make a proper bibliography**Your grade will be determined by how well you communicate what you have learned about your organelle. See the rubric below. 1234Understanding/ContentX2This one counts as doubleThe person’s understanding of the topic is so incomplete or has so many misconceptions that the person cannot be said to understand the topic.The person has incomplete understanding of the topic and/or misconceptions about some of the information; however, the person maintains a basic understanding of the topic.The person has a complete understanding of the information important to the topic but not in great detail.The person has demonstrated a complete and detailed understanding of the cell part and function within the municates Effectively in Written FormThe communication demonstrates little or no attention to the use of necessary conventions* of writing. Errors are distracting.The person does not use some required conventions* of writing or demonstrates errors in use of some conventions. Some errors may be distracting.The person uses all necessary conventions* of writing for enhanced readability with few errors.The person uses all necessary conventions* of writing without error. Spelling, punctuation, capitalization, grammar, usage, and paragraphing add to the overall quality of the communication. Some conventions may be manipulated for effect.AssignmentThe person is not punctual in turning in the assignment and the assignment is not typed and does not follow the suggested format.The person is not punctual in turning in the assignment or the assignment is not typed and does not follow the suggested format.The assignment is neatly typed but does not follow the suggested format. The person is punctual in turning in the assignment.The assignment is neatly typed and follows the suggested format. Assignment is turned in on time or early.CreativityAssignment lacks interesting, creative, or humorous details.Assignment meets the requirements, but is somewhat lacking in interesting, humorous, or creative details.Some relationships and details about the particular cell part are communicated in a creative way using the prescribed format.The assignment shows relationships and details about the particular cell part in an unusual, original, or creative fashion…wow factor is present Name:Cell Part:Evaluate your work—fill out this rubric as if you were grading yourself. Turn in your rubric with your project.*WRITING CONVENTIONS include spelling, punctuation, capitalization, grammar, and paragraphing. The writer should use conventions to enhance the readability of the paper. Spelling should be correct on all words. Punctuation should be smooth and guide the reader through the paper. Capitalization should be used correctly. Paragraphing should reinforce organization. The writer may manipulate conventions for effect. ................
