BIOL CHPTR 4 HW P2

Part 2: A metaphor is a comparison of one thing to another.  A good metaphor helps us understand the two things more clearly.  (For example, the atom is sometimes compared to a miniature solar system; the solar system is a metaphor for the atom.  Each part of the atom matches up with a part of the solar system).

For this assignment, you will be creating a metaphor relating a cell to something else.

You may choose a plant or animal cell. Your job is to think of a good metaphor that helps you understand the organelles in a cell and their functions, and then use that metaphor to explain what a cell is and how it works.  You must include all the organelles listed for the cell type in your metaphor and answer all the questions below for full credit.

It is a good idea to stick to something you are interested in or know a lot about. For example, I had a student who was a huge Boston Red Sox fan. Her metaphor was using Fenway park as the cell and different aspects of that for the parts of the cell: the shortstop, the popcorn seller, the dugout, the stands, etc. Please do not use this example as your metaphor!

1. Brief overview or introduction to your metaphor.  Don’t forget to say whether you are representing a plant cell or animal cell.

2. Give a more detailed explanation of each part of the cell and how it fits into the metaphor. 

If you choose an animal cell, the following organelles must be included in your metaphor:

nucleus
plasma membrane
cytoplasm
cytoskeleton
rough ER
smooth ER
ribosome
Golgi apparatus
mitochondria
lysosome
peroxisome
1 type of cell junction
extracellular matrix
flagella (optional)

If you choose a plant cell, the following organelles must be included in your metaphor:

nucleus
plasma membrane
cytoplasm
cell wall
rough ER
smooth ER
ribosome
Golgi apparatus
mitochondria
central vacuole
chloroplast
plasmodesmata
