 * = **Standards** || * //**Performance Indicator 4.4: Observe and describe cell division at the microscopic level and its macroscopic effects**//
 * **4.4a: In multicellular organisms, cell division is responsible for growth, maintenance, and repair. In some one-celled organisms, cell division is a method of asexual reproduction.**
 * **4.4b: In one type of cell division, chromosomes are duplicated and then separated into two identical and complete sets to be passed to each of the two resulting cells. In this type of cell division, the hereditary information is identical in all the cells that result.**
 * **4.4c: Another type of cell division accounts for the production of egg and sperm cells in sexually reproducing organisms. The eggs and sperm resulting from this type of cell division contain one-half of the hereditary information.**
 * **4.4d: Cancers are a result of abnormal cell division.**
 * **//Performance Indicator 5.1: Compare the way a variety of living specimens carry out basic life functions and maintain dynamic equilibrium//**
 * **5.1c: All organisms require energy to survive. The amount of energy needed and the method for obtaining this energy vary among cells. Some cells use oxygen to release the energy stored in food.**
 * **//Performance Indicator 6.2: Provide evidence that green plants make food and explain the significance of this process to other organisms.//**
 * **6.2a: Photosynthesis is carried on by green plants and other organisms containing chlorophyll. In this process, the Sun's energy is converted into and stored as chemical energy in the form of a sugar. The quantity of sugar molecules increases in green plants during photosynthesis in the presence of sunlight.**
 * **6.2b: The major source of atmospheric oxygen is photosynthesis. Carbon dioxide is removed form the atmosphere and oxygen is released during photosynthesis.**
 * **6.2c: Green plants are the producers of food which is used directly or indirectly by consumers.** ||  ||
