Cells: The Smallest Living Unit of Humans and Other Organisms

General Objectives and Study Guide

Your objectives for will include those presented in your textbook unless modified here at a later date.

Textbook Readings: Chapter 3 of Marieb (2004) or Marieb and Hoehn (2008)Study your textbook readings and other assigned materials for this material. You will have the opportunity to hear lecture discussion and to ask questions in lecture to clarify your understand. It will be up to you to study hard and then ask questions. By doing this, you can help me help you by focusing our discussions on the knowledge and concepts you are having the most difficulty grasping.

Links to Study Resources for Cytology from Other Life Science Classes (such as General Zoology).

Note that all references in these pages to "Units" and "Parts" are for other courses, not our AP2124 course; all of the topics addressed in the links below ARE covered in Chapter 3 of your textbook (Marieb and Hoehn 2008).

• Introduction to Cell
• DNA Structure (Review) & Function
• RNA Structure & Function; Protein Synthesis, Mutations
• Cellular Metabolism (Note that this is covered only briefly in Chapter 3 of your textbook. The details of cellular metabolism will be covered in APII, thus you do not need to know the details of such things as glycolysis, the Kreb's Cycle, electron transport, etc. at this time.)
• Homeostasis: The Cell Membrane
• Mitosis
  

Related Links with Optional Study Resources

The following link provides graphics and text on cell topics similar to our lectures and textbook readings. It is not required, but may be useful for you as an additional study resource. Note that the Chapter 3 heading at the start of the web site is purely coincidental in its relationship to our chapter numbers.
