Cell Organelles ( Part 1)

List the organelles and structures found in cells. Pick one organelle and describe the role it plays in the life of the cell. In your description, comment on what may happen to the cell if the organelle did not function properly. (75 words or more)

Written Assignment: Eukaryotic and Prokaryotic Cells ( Part 2)

Module 2 introduces you to the living cell. Compare and contrast eukaryotic and prokaryotic cells.

Your assignment should be 250-500 words in length.

Please No Plagiarism!!!!! In your own words!!!!!

(show all your works and please do all questions from part a to part e below. Sorry for long questions, but I will thanks to anyone who can help me all questions from part a to part e below)

a. What four structures are found in all cells?

b. What are examples of prokaryotic cells? How are they different from eukaryotic cells?

c. Compare and contrast plant and animal cells

d. Know the role of each organelle in the endomembrane system

e. What is the role of mitochondria and chloroplasts? Why are they not part of the endomembrane system?

In order to understand how cells function, we often have to use analogies to everyday items or processes to explain the jobs of the various organelles. In this assignment, we're asking you to determine which everyday items that you can find around the house (from your kitchen/desk drawers, backpack, a recycling bin, food, etc.) to represent the organelles inside a cell, and to assemble those items into a 3-dimensional representation of a eukaryotic (plant or animal) cell. Think about how the items you're using can best represent the various parts of the cells and their functions. For example, what does the mitochondria do? What household item do you have that is analogous, or could represent that function?

Note that the items that you find may or may not visually resemble their cellular counterparts. It's fine if they don't - we’re looking for you to demonstrate to us that you know what the various organelles do, and that you can think creatively about what objects fill that role in your house or in your life. Therefore, your finished "model" may not look much (or at all) like the diagram of a cell from your textbook! However, if the spatial organization of organelles is important (e.g. if one type of organelle is always located next to another), we do expect to see that reflected in your model.

Your model will need to include:

A picture (or pictures) of your model. The picture(s) must contain your name written on a piece of paper next to your model. If you'd like, include a picture of yourself with your model. (A cell-fie!)

Proper identification of the cell (is it a plant or animal cell)?

For each organelle/structure:

Correct labeling/identification of the structure in your image/video

A description of the organelle's function, which should be in YOUR OWN WORDS, not copied from the book, lectures, or other sites.

A justification for why the object that you chose to represent each organelle is a good analogy for that organelle's function.

Attention to quality and creativity – which will weigh into the overall evaluation.

You can do this in a text document, a powerpoint presentation, or a short video in which you verbally explain your model (be sure to include your name in the video!). Note that you will NOT receive credit for a drawing of a cell or a collage or collection of images found online. Any images you submit must be completely original and made by you. Your name should be in any document and/or picture you submit. Submissions without names will receive reduced credit.

This is NOT intended to be a burdensome exercise, nor should you need to purchase any materials to complete this assignment - I would like for it to be a fun way for you to practice working with the different types of organelles and their structures and functions, and to think creatively about the materials you have on hand.
