introductionCell Structure and structure and function of plasma membranes

Overview

Welcome, this week we will be studying cellular structure and the structure and function of plasma membranes (cell membranes). We will study the similarities and differences between prokaryotic and eukaryotic cells and the complex systems within cells which help cells maintain homeostasis. We will gain insight into the importance of cellular membranes and learn how cells are able to transport materials across the cell membrane with and without the use of energy. Lastly, we will gain insight into the modern cell theory.

By the end of this module you should be able to do the following:

Chapter 4

Describe the role of cells in organisms
Compare and contrast light and electron microscopy
Summarize the cell theory
Name examples of prokaryotic and eukaryotic organisms
Compare and contrast prokaryotic and eukaryotic cells
Describe the relative sizes of different cells
Explain why cells must be small
Describe the structure of eukaryotic cells
Compare and contrast animal with plant cells
State the role of the plasma membrane
Summarize the functions of the major cell organelles
List the components of the endomembrane system
Recognize the relationship between the endomembrane system and its functions
Describe the cytoskeleton
Compare and contrast roles of microfiliments, intermediate filaments, and microtubules
Compare and contrast cilia and flagella
Summarize the differences among the components of prokaryotic cells, animal cells, and plant cells

Chapter 5:

Understand the cell membrane fluid mosaic model
Describe phospholipid, protein, and carbohydrate functions in membranes
Discuss membrane fluidity
Explain why and how passive transport occurs
Understand the osmosis and diffusion processes
Define tonicity and its relevance to passive transport
Understand how electrochemical gradients affect ions
