| In this unit students explore cells, the fundamental components of living things. They perform chemical tests to determine the major macromolecules of which cells are composed. Students describe the building blocks of each type of macromolecule and examine the functions that these macromolecules have in cells. Through experimentation and model building they learn how these cell functions determine that of the organism. Students learn that all cells come from pre-existing cells. |

| B1.2 Scientific Reflection and Social Implications B1.2C Develop an understanding of a scientific concept by accessing information from multiple sources. Evaluate the scientific accuracy and significance of the information. B2.1x Cell Differentiation B2.1d Describe how, through cell division, cells can become specialized for specific function. B2.2A Explain how carbon can join to other carbon atoms in chains and rings to form large and complex molecules. B2.2B Recognize the six most common elements in organic molecules (C, H, N, O, P, S). B2.2C Describe the composition of the four major categories of organic molecules (carbohydrates, lipids, proteins, and nucleic acids). B2.2D Explain the general structure and primary functions of the major complex organic molecules that compose living organisms. B2.2E Describe how dehydration and hydrolysis relate to organic molecules. B2.2f Explain the role of enzymes and other proteins in biochemical functions (e.g., the protein hemoglobin carries oxygen in some organisms, digestive enzymes, and hormones). B2.4f Recognize and describe that both living and nonliving things are composed of compounds, which are themselves made up of elements joined by energy-containing bonds, such as those in ATP. B2.5 Living Organism Composition B2.5A Recognize and explain that macromolecules such as lipids contain high energy bonds. B2.5g Compare and contrast plant and animal cells.
