UNIT 7: GROWTH & DEVELOPMENT

Many of life’s little chores such as sweeping and dusting, are quietly satisfying and rather fun.  Washing dishes by hand, however, is never fun, which is why come clever person made the dishwasher.  This handy invention soaks, washes, and rinses your dishes to a spot-free, sanitary sparkle.  You unload the dishes, and the machine is ready to start the cycle all over again.  A cell goes through a cycle, too.  This cycle of growth, DNA synthesis, and division is essential for an organism to grow and heal.  If it goes out of control, abnormal cell growth may occur, resulting in cancer cells like those shown to the right.  (McDougal Littell)  Chapter 5
