Cell Biology
(Chapters 4 & 5)

Cell Biology is the study of the cell, the basic unit of all life. Therefore an understanding of the cell is at the core of understanding biology. All living things can be categorized as being either a prokaryotic cell, a eukaryotic cell, or a collection of eukaryotic cells. This unit explores the basic constituents of the cell and how they work together to allow a cell to live and function. By the end of this unit a student should be familiar with the basic internal structures and organelles of a cell and how they function to support the cell, the basic unit of all life.
