Organisms are made up of simpler units called cells. Organisms need light and/or chemicals to make cellular protoplasm. Organisms obtain and use energy through photosynthesis or cellular respiration to carry out their life processes. Organisms release waste chemicals produced by cells. Organisms seek to maintain homeostasis at all biological levels of organization. Organisms grow, develop and eventually die Organisms can reproduce their own kind using DNA. Organisms adapt to changes Performance Activities/Assessments Vocabulary Compare and contrast the cellular structures and degrees of complexity of prokaryotic and eukaryotic organisms.

Cells function as microscopic chemical factories synthesizing and degrading biological molecules necessary for life. Liquid water forms hydrogen bonds, is a solvent, and forms hydronium ions allowing a wide range of biochemical reactions to occur. Biological molecules produced by a cell can be used by the cell or transported outside for use by other cells. Cells are composed mostly of: C, H, N, O, P, and S. Performance Activities/Assessments Vocabulary Identify the initial reactants, final products, and general purposes of photosynthesis and cellular respiration.

7 Standards 3.1.B.4A 3.1.B.A.1 Content (Big Ideas) Essential Questions Key Concepts Cells have organized structures and systems necessary to support chemical reactions needed to maintain life. EQ: How does life result from cellular structure and function? Cells are the basic unit of structure and function for all living things. Cells occur in two basic forms: Prokaryotes (Bacteria and Archaea) and Eukaryotes (all other cells). A cell s interior is separated or compartmentalized from the environment by a phospholipid bilayer plasma membrane. The cytoplasm contains a collection of connected, internal membranous sacs that divide the cytoplasm into functional and structural compartments or organelles. Performance Activities/Assessments Vocabulary Explain how all organisms begin their life cycles as a single cell and that in multicellular organisms, successive generations of embryonic cells form by cell division. Summarize the stages of the cell cycle. Examine how interactions among the different molecules in the cell cause the distinct stages of the cell cycle which can also be influenced by other signaling molecules. Explain the role of mitosis in the formation of new cells and its importance in maintaining chromosome number during asexual reproduction. Compare and contrast a virus and a cell. Relate the stages of viral cycles to the cell cycle.

8 Chemical reactions and processes necessary for life are carried out in cytoplasm or organelles within a eukaryotic cell s protoplasm. Structure is related to function at the cellular and organelle levels of biological organization. Cells come only from the division of a pre existing cell. Relate the structure of cell organelles to their function (energy capture and release, transport, waste removal, protein synthesis, movement, etc) Explain the role of water in cell metabolism. Explain how the cell membrane functions as a regulatory structure and protective barrier for the cell.

9 Standards A Content (Big Ideas) Essential Questions Key Concepts Eukaryotic cells can differentiate and organize making it possible for multi cellularity EQ: What are the advantages of multicellularity? A multicellular organization enables life functions such as movement, digestion, internal circulation of nutrients, excretion of waste and reproduction to be subdivided among specialized groups of cells. The simplest level of multicellular organization is a tissue. Different types of cells and tissues combine to form distinct structures known as organs which perform specific functions. Organs work together as a system to perform common functions. Cells that have differentiated to perform specialized functions rely on the collective function of other specialized cells within a multicellular organism to maintain their living condition. Performance Activities/Assessments Vocabulary Explain how cells differentiate in multicellular organisms. Describe and interpret relationships between structure and function at various levels of organization.

11 Standards A A2 Content (Big Ideas) Essential Questions Key Concepts Organisms obtain and use energy to carry out their life processes. EQ: How do different organisms obtain and use energy to survive in their environment? Forms of energy are required to maintain life. The energy flow of biochemical reactions is governed by the physical laws of thermodynamics. Most biochemical reactions require an input of energy. Photosynthesis is the process that transforms light energy into potential chemical energy. Cellular respiration is the process by which potential chemical energy in the bonds of glucose is transformed into potential chemical energy in the bonds of ATP. ATP molecules store usable chemical energy to drive life processes through coupled reactions. Glycolysis is the foundation of both aerobic and anaerobic respiration. Glycolysis, through anaerobic Performance Activities/Assessments Vocabulary Compare and contrast the basic transformation of energy during photosynthesis and cellular respiration.

13 Standards A5 Content (Big Ideas) Essential Questions Key Concepts Through a variety of mechanisms organisms seek to maintain a biological balance between their internal and external environments. EQ: How do organisms maintain a biological balance between their internal and external environments? Homeostasis dynamically returns biological changes (body temperature, osmolarity, blood pressure, ph, blood glucose, etc.) to balance by modifying chemical reactions, adjusting energy transformations, and responding to environmental changes. Molecules, ions and water move in and out of the cell through a variety of mechanisms. Passive transport depends on the diffusion of substances with a concentration gradient moving across a membrane from an area of higher concentration to an area of lesser concentration without energy. Performance Activities/Assessments Vocabulary Describe transport mechanisms across the plasma membrane. Explain the consequences of extreme changes in ph and temperature on cell proteins. Identify and describe the cell structures involved in the transport of materials into, out and throughout the cell.

14 Both passive and facilitated diffusion move materials along a concentration gradient without energy. Osmosis is the diffusion of water from an area of lower solute concentration (more aqueous solution) across a membrane to an area higher solute concentration (less aqueous solution). Active transport moves atoms, ions and small molecule mostly against a concentration gradient and requires an expenditure of energy.

15 Standards B A Genetics Content (Big Ideas) Essential Questions Key Concepts New cells arise from the division of pre existing cells. EQ: How do cells grow and reproduce? Cells grow when they can take in more nutrients through their plasma membranes than they can metabolize in their interior. Cells may divide when their metabolism exceeds nutrient absorption. All cells go through a cell cycle. Prokaryotic cells divide via binary fission. Eukaryotic cells first divide their nucleus and then divide their cytoplasm to make new cells. Cell differentiation occurs many times during development of a multicellular organisms giving rise to a diversity of cell types. Performance Activities/Assessments Vocabulary Explain that the information passed from parents to offspring is transmitted by means of genes which are coded in DNA molecules. Explain the basic process of DNA replication. Describe the basic processes of transcription and translation. Explain how crossing over, jumping genes, and deletion and duplication of genes results in genetic variation. Explain how mutations can alter genetic information and the possible consequences Class Notes Class Activities Laboratory Activities Tests/Quizzes Posters Presentations 3-D models Power points Internet Activities Culmination Projects Graphic Organizers Videos Handouts DNA Genes Chromosomes Mitosis Cell Cycle Binary Fission Transcription Translation RNA Mutation

17 Standards B Genetics Content (Big Ideas) Essential Questions Key Concepts Heredity information in genes is inherited and expressed. EQ: How is the hereditary information in genes inherited and expressed? Sexually reproducing organisms produce gametes which transport hereditary information from one generation of organisms into another generation. Meiosis involves a two step nuclear division reducing the number of chromosomes in half producing gametes. One or more pairs of genes on one or more chromosomes code for the expression of inherited traits. Two or more versions of a gene (alleles) contribute to the expression of inherited traits. During the process of meiosis genetic recombinations may occur contributing to genetic variability within a population. Performance Activities/Assessments Vocabulary Describe how the process of meiosis results in the formation of haploid gametes and analyze the importance of meiosis in sexual reproduction. Compare and contrast the function of mitosis and meiosis. Illustrate the sorting and recombining of genes in sexual reproduction results in a great variety of possible gene combinations in offspring. Describe the basic structure of DNA, including the role of hydrogen bonding.

18 Patterns of inheritance reflecting how genes interact and express themselves (including dominant, recessive, codominance, incomplete dominance, sexlinked, sex influenced, multiple alleles) can be predicted, observed and described. The Punnet square is a tool that can be used to predict the probability of an offspring s genotype and phenotype Explain how the process of DNA replication results in the transmission and conservation of the genetic code. Describe how transmission and translation result in gene expression. Differentiate among the end products of replication, transcription, and translation.

19 Standards B B Genetics Content (Big Ideas) Essential Questions Key Concepts DNA segments contain information for the production of proteins necessary for growth and function of cells. EQ: Why is DNA called the blueprint of life? The basic molecular and the associated genetic code structure of DNA are universal, revolutionizing our understanding of disease, heredity and evolution. DNA contains the complete set of instructions, the genetic code, for building and running an organism. RNA is necessary for protein synthesis from DNA. Many synthesized polypeptides require additional processing to acquire their active, threedimensional structures. Which genes are expressed at a given time is determined by the integration of internal and environmental signals received by a cell. Enzymes are special proteins designed to catalyze most biochemical reactions that Performance Activities/Assessments Vocabulary Cite evidence to support that the genetic code is universal. Explain how genetic technologies have impacted the fields of medicine, forensics, and agriculture.

21 Standards 3.1.B.C C1 Evolution Content (Big Ideas) Essential Questions Key Concepts Evolution is the result of many random processes selecting for the survival and reproduction of a population. EQ: How do we scientifically explain the evidence and mechanisms for biological evolution? Mutations alter a gene's genetic information, resulting in a change in the protein that is made, or how or when a cell makes that protein. Most mutations are evolutionary neutral. Evolution occurs when the gene frequency of alleles in a population shifts to confer survival and reproductive success. The differential reproductive success of populations of organisms with advantageous traits is known as natural selection. Performance Activities/Assessments Vocabulary Describe species as reproductively distinct groups of organisms. Analyze the role that geographic isolation can play in speciation. Explain how evolution through natural selection can result in changes in biodiversity through the increase or decrease of genetic diversity within a population. Describe how the degree of kinship between species can be inferred from the similarity in their DNA sequences.

22 Speciation occurs when one population is isolated from another population. The isolation can be geological, reproductive, or filling different ecological niches to reduce competition. With isolation comes changing environmental factors exerting selective pressure on mutations and adaptations. Common anatomical and/or genetic structures and behaviors demonstrate that species have evolved from common ancestors. The fossil record documents patterns of mass and background extinctions and the appearance of new species. There are similarities and differences between fossils and living organisms. Selective breeding and biotechnology contribute to the deliberate changing of the genetic makeup of a population. primitive prokaryote about 4 billion years ago and that for the next 2 billion years, a huge diversity of single celled organisms evolved. Analyze how increasingly complex, multcellular organisms evolved once cells with nuclei developed. Describe how mutations in sex cells may be passed on to successive generations and that the resulting phenotype may help, harm, or have little or no effect on the offspring s success in its environment. Describe the relationship between environmental changes and changes in the gene pool of a population.

24 Standards Ecology 3.1.B.A, and 4.1 Content (Big Ideas) Essential Questions Key Concepts Organisms on Earth interact and depend in a variety of ways on other living and nonliving things in their environments. EQ: How do organisms interact and depend on each other and their environment for survival? All forms of life on Earth are connected in a Biosphere. Specific biotic and abiotic factors characterize biomes and their component ecosystems. Organisms and their environment are interdependent. Sunlight is the initial energy source for most life on Earth. Energy is converted from one form to another as it moves through a food chains and food webs. Matter flows through an ecosystem using a variety of natural cycles. Limiting factors can cause population fluctuations or extinction in a given ecosystem.
