Structure and Function of Cells Broad Concept: All living things are composed of cells. Life processes in a cell are based on molecular interactions. 2. Structure and Function of Cells Students will: Relate cell parts/organelles to their functions. * Differentiate between prokaryotic cells and eukaryotic cells, in terms of their general structures and degrees of complexity. * Distinguish between plant and animal cells. * Describe how cells function in a narrow range of physical conditions, such as temperature and pH, to perform life functions that help to maintain homeostasis. Explain the role of cell membranes as a highly selective barrier (diffusion, osmosis, and active transport). * Identify the reactants and products in the general reaction of photosynthesis. Describe the use of isotopes in this identification. Provide evidence that the organic compounds produced by plants are the primary source of energy and nutrients for most living things. * Identify how cellular respiration is important for the production of ATP. Explain the interrelated nature of photosynthesis and cellular respiration. * Describe and compare the processes of mitosis and meiosis, and their role in the cell cycle. * Instructional Strategies/Formative Assessments • Protist Lab — examine, compare, and contrast a variety of single-celled organisms • Prepared slides of tissues — examine, compare and contrast differentiated cell types • Liver Lab— enzyme function • Potato Lab — osmotic balance • Bubble Membranes — model properties of a fluid mosaic membrane • Osmotic Egg — investigation of osmosis • Plasmolysis lab — investigate osmosis and semipermeability of membranes in living cells • Chloroplast extraction — examination of properties of a cellular organelle • Plant color on other planets Summative Assessments Cell City — model functions of cellular organelles Cell catalogue — identify structure, function, and importance of cellular organelles Cell specialization posters Organelle analogies • Mitosis and Meiosis Flip books — compare and contrast these two processes of cell reproduction 3. Genetics Broad Concept: Genes are a set of instructions encoded in the DNA sequence of each organism that specify the sequence of amino acids in proteins characteristic of that organism. 3. Genetics Students will: Describe the structure and function of DNA, and distinguish among replication, transcription, and translation. * Describe the processes of replication, transcription, and translation and how they relate to each other in molecular biology. Describe the general pathway by which ribosomes synthesize proteins by using tRNAs to translate genetic information encoded in mRNAs. Explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. Differentiate between dominant, recessive, codominant, polygenic, and sex-linked traits. State Mendel’s laws of segregation and independent assortment. Use a Punnett Square to determine the genotype and phenotype of monohybrid crosses. * Explain how zygotes are produced in the fertilization process. Recognize that while viruses lack cellular structure, they have the genetic material to invade living cells. Instructional Strategies/Formative Assessments • DNA molecular models • Sex in class (Making babies) — assign genotypes and phenotypes, mix and match within the gene pool • Allelic frequencies — collect data on frequency of various phenotypes; extrapolate genotypes, and discuss HardyWeinberg principle • Recessive lethal allele Lab — demonstrate persistence of recessive lethal alleles (probability) • Gattacca — introduce bioethical issues • DNA gels — introduction to biotechnology Summative Assessments Dragon molecular genetics — transcribe and translate stretches of genetic code Personal pedigrees — tracae traits in a family Disease in a glass — model disease transmission and reconstruct path of infectivity Genetic Disease reports/posters/presentations — research project requiring application of knowledge of genetics 4. Human Anatomy and Physiology Broad Concept: There is a relationship between structure and function in organ systems of humans. 4. Human Anatomy and Physiology Students will: Explain how major organ systems in humans (e.g., kidney, muscle, lung) have functional units (e.g., nephron, sarcome, alveoli) with specific anatomy that perform the function of that organ system.

Evolution and Biodiversity Broad Concept: Evolution and biodiversity are the result of genetic changes that occur in constantly changing environments. 5. Evolution and Biodiversity Students will: Explain how the fossil record, comparative anatomy, and other evidence support the theory of evolution. Illustrate how genetic variation is preserved or eliminated from a population through Darwinian natural selection (evolution) resulting in biodiversity.
