Document Summary

Theme 1 for biology 1a03 is the structure of the cell - all types of cells. In module 1, we will focus on the composition and structure of membranes. The learning objectives in this module are to: Every one of us began as a single cell just like this cell here - the result of the union of an egg and sperm. As we watch this movie of a fertilized egg under the microscope, we can see mitotic cell division creating two cells, then four cells. Eventually, continued cell division allows us to reach an estimated 10 trillion cells as an adult. Each cell shares the same genetic heritage as the original fertilized cell, however, these cells differ in function. They may be muscle cells, skin cells, kidney cells and neurons. These are all eukaryotic cells, a classification that means the cells have a nucleus that contains most of the genetic material in the cell.
