BIO-QUEST: Cell Biology
Directions: In this module, we will explore the basic units of life, their structure, function, and energy processes. To do this, you are going to explore a variety of resources, including your text, videos, and websites, to find answers to questions provided. The Bio-Quest is your guide to discovery in our modules and serves to help you navigate the material and focus on the key elements, big concepts, and enduring ideas surrounding each topic. Part one of the quest is your study guide to help you navigate the materials. It is NOT graded. Part two is your graded assignment for the module and will be submitted for 25 points as assigned by the grading rubric for Assignments.
PART ONE (Not graded-for use as notes)
I. Watch the video: Intro to Cells http://www.youtube.com/watch?v=gFuEo2ccTPA
1. Predict: How does understanding how cells work improve our survival as a species?
II. Use these resources to answer the questions below:

Cell History and Theory
2. Briefly describe each person's contribution to our knowledge of cells. a. Robert Hooke b. Anton van Leeuvenhoek c. Robert Brown d. Albrecht von Roelliker e. Carl Heinrich Braun f. Earnest Everett Just g. Lynn Margulis
3. What are the three postulates of the cell theory and who is credited with each part?
Cell Structure and Function
4. What things do all cells have in common?
5. What is the role of the cell membrane? How does its structure enable the cell to survive?
6. Complete the chart comparing and contrasting prokaryotic and eukaryotic cells:
7. Compare the cell to something in your life (house, work, body, etc). What items would the organelles represent in that situation? Write an analogy for the organelles in the space provided, telling what role the organelle would play, and how the function of the organelle and the function of the role are alike (Example: The nucleus would be like the human brain because it controls the cell and the brain controls the body)
b. Rough Endoplasmic Reticulum
c. Smooth Endoplasmic Reticulum
d. Golgi Body (Golgi Apparatus)
h. Cell Membrane
i. Cell Wall
j. Central Vacuole
8. Compare and contrast passive and active transport. (focus on particle type, size, energy, and two examples of each)
9. Complete the chart on Tonicity:
Which means there is more water:
