Essential Questions How does cellular structure impact the function of life? How does energy flow freely through biological systems? Why is cellular reproduction essential to life? Enduring Understanding with Unit Goals EU# 1: Interactions within biological systems lead to complex properties. o Understand the structure and function of subcellular components and their interactions provide essential cellular processes. o Explore Eukaryotic cells membrane bound organelles to create specialized regions. EU# 2: Homeostasis require that cells create and maintain internal environments. o Explain that cell membranes are selectively permeable due to their structure. o Understand that growth and dynamic homeostasis are maintained by the constant movement of molecules across cellular membranes. o Explore how organisms exchange matter with the environment to grow, reproduce and maintain organization. EU# 3: Heritable information provides for continuity of life. o Visually demonstrated how in eukaryotes pass their heritable information from one generation to the next via processes that include the cell cycle and mitosis or meiosis plus fertilization. o Understand that in the cell cycle is a complex set of stages that is highly regulated with checkpoints, which determine the ultimate fate of the cell. o Explore the cell cycle and how Mitosis passes a complete genome from the parent cell to daughter cells. o Explain the steps of Meiosis, a reduction division, followed by fertilization and how this ensures genetic diversity in sexually reproducing organisms. 1

CCSS.ELA-Literacy.RST.11-12.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks; analyze the specific results based on explanations in the text. CCSS.ELA-Literacy.RST.11-12.4 Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 11-12 texts and topics. CCSS.ELA-Literacy.RST.11-12.8 Evaluate the hypotheses, data, analysis, and conclusions in a science or technical text, verifying the data when possible and corroborating or challenging conclusions with other sources of information. Next Generation Science Standards: HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms. HS-LS1-5. Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy. HS-LS1-7. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy. HS-LS1-4. Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.

Unit Content Overview Campbell Chapters: 4-10 EU# 1: Structure and function of subcellular components o Types Cells: Prokaryote vs. Eukaryote o Organelles: Anatomy and Physiology of all organelles and cellular structures. EU# 2: Cell Membrane: Anatomy and Physiology, Passive Transport, Active Transport. o Cell membranes, Cell walls o Passive transport, active transport and facilitated diffusion. o Hypertonic, hypotonic, or isotonic solutions. o Endocytosis and Exocytosis cellular transport. EU# 3: Cell Cycle (Mitosis and Meiosis) o Stages and what cells look like during the cell cycle. o Meiosis, a reduction division, followed by fertilization ensures genetic diversity in sexually reproducing organisms. Learning Objectives Students will be able to Summarize the differences between prokaryotic and eukaryotic cells. Explain how internal membranes and organelles contribute to cell functions. Construct models that connect the movement of molecules across membranes with membrane structure and function. Demonstrate with models and pose scientific questions about the properties of cell membranes and selective permeability based on molecular structure. Demonstrate with models and pose scientific questions about what mechanisms and structural features allow organisms to capture, store and use free energy. Construct explanations of the mechanisms and structural features of cells that allow organisms to capture, store or use free energy. Evaluate data to show the relationship between photosynthesis and respiration in the flow of free energy through a system. Understand that carbon and nitrogen move from the environment to organisms where it is used to build carbohydrates, proteins, lipids, or nucleic acids. Describe using evidence the events that occur in the cell cycle. Construct and explanation, using visual representations or narratives, as to how DNA in chromosomes is transmitted to the next generation via mitosis, or meiosis followed by fertilization. Construct a representation that connects the process of meiosis to the passage of traits from parent to offspring. 3
