Chapter 3: Anatomy of Cells
Simply stated, cell theory asserts that the cell is the fundamental organizational unit of life.
Common cell structures and their functions are examined in this chapter. The approach is general, and the
model of the "composite cell" is useful for an overall understanding. Such components as cell membranes,
cytoplasm, organelles, cytoskeleton, nucleus, and cell connections are previewed in some detail.
Objectives
After students have completed this chapter, they should be able to:
1.
Discuss the structure of a typical cell.
2.
Describe the molecular structure and function of cell membranes.
3.
Identify by name the membranous and nonmembranous organelles of the cell.
4.
Discuss the structure and function of the following: endoplasmic reticulum, ribosomes, Golgi
apparatus, mitochondria, lysosomes, peroxisomes, cytoskeleton, cell fibers, centrosome, centrioles, cell
extensions, nucleus, and cell connections.
5.
Discuss the organization and generalized function of chromatin material in the nucleus.
6.
Describe the different types of cell connections.
