Chapter 6. A Tour of the Cell

(pp 93-123)

Main Points and Concepts

All organisms that we know about are made up of one or more cells.

All cells are related to one another through billions of years of evolution.

Cooperation between and among cells is an important evolutionary advantage.

Cells contain compartments and organelles that allow specialization.

Eukaryotic cells are much more complex than prokaryotic cells.

Also see summary of key concepts on page 121-122.

Learning goals

Students will be able to define and explain the basic terms and concepts associated with the structure and function of eukaryotic and prokaryotic cells.

Students will be able to distinguish between prokaryotic and eukaryotic cells and explain their differences.

Students will be able to outline the major organelles and functional assemblies of organelles in eukaryotic cells, including a brief description of their microscopic appearance, their structure and their function.

Students will be able to provide a brief description of the 3-domain system of classification, the Universal Tree (and the methodology used to derive it) and the endosymbiont theory.

Students will be able to outline and explain the Cell Theory, including all major points and corollaries.

Students will be able to explain the principle of compartmentalization at the cellular level.

Students will be able to explain the surface area to volume ratio problem that all cells face.
