Document Summary
Objective 1 define cell specialization and describe its importance to an organism. All cells are similar early in development. The body begins as a single fertilized egg, or cell. The cells eventually divide unevenly, producing a size difference, and then take on different shapes. Cell specialization the tendency of a particular cell type to have a special shape or structure which is related to the special functions the cell carries out. Specialization first occurs during the embryonic and fetal development, but continuous as certain specialized cells are produced by other non-specialized cells which are dividing. Cell specialization increases the efficiency of the body. One cell cannot carry out all of the functions. With different cell types for different functions, the speed and effectiveness of activities increases. Objective 2 describe the general characteristics of each of the following cell types and relate their characteristics to their functions. Conducts electrical impulse from one body part to another.
