Life Processes Identify and define the seven life processes (MRS GREN). Classification Group living organisms based on observed similarities and differences. Classify vertebrates into taxonomic groups based on visible physical characteristics. Construct a dichotomous key to classify vertebrates. Cells Compare the structure of generalised plant and animal cells, and selected microbes (e.g. bacteria, fungi and Amoeba) Distinguish among cell wall, cell membrane, nucleus, cytoplasm, temporary and permanent vacuoles, mitochondrion, chloroplast, endoplasmic reticulum and ribosomes. Relate the structure of organelles to their functions; Identify specialised cells such as blood cells, ciliated epithelial cells, nerve cells, root hair cells, sperm cells and egg cells. Explain the importance of cell specialisation in multicellular organisms; include hierarchy of cells, tissues, organs; organ systems and then organism Diffusion, Osmosis, Active transport and Osmoregulation Explain the processes of diffusion, osmosis and active transport. Identify everyday instances of these processes occurring. Discuss the importance of diffusion, osmosis and active transport in living systems. Nutrition in Plants Describe the process of photosynthesis in green plants; test for end products, starch or reducing sugar (glucose). Relate the structure of the leaf of a flowering plant to its function in photosynthesis; draw and label the external features and the internal structure (cross section) of a leaf as seen in cross section under the light microscope. Nutrition in Humans Discuss the importance of a balanced diet in humans. State components of a balanced diet (carbohydrates, fats, proteins, vitamins and minerals, water and roughage and their roles) along with the results of their deficiency or surplus. Suggest dietary recommendations for treating and preventing named deficiency and physiological diseases (such as those outlined in the manual and your notes). Perform tests to distinguish among food substances - Test for proteins (Biuret), fats (grease spot), starch (iodine), reducing sugars (Benedict’s solution). The Digestive System in Humans Relate the structures of the human alimentary canal to their functions; Draw and label simple diagrams of the alimentary canal and internal structure of a tooth required. Describe mastication and the role of teeth in the mechanical breakdown of food to be included. (Compare types of teeth in humans and compare types of teeth in herbivores and carnivores.) Explain the role and importance of enzymes role of digestive enzymes in the mouth, stomach and pancreatic enzymes in the small intestine. Discuss properties of enzymes. Deduce from tables and graphs the effects of temperature and pH on enzyme activity. Experimental Skills Follow all drawing rules as outlined in the drawing skills checklist posted in the classroom (including calculation of magnification).SB2. Obtain, evaluate, and communicate information to analyze how genetic information is expressed in cells. a. Construct an explanation of how the structures of DNA and RNA lead to the expression of information within the cell via the processes of replication, transcription, and translation. Learning Targets _______Identify the structural components of DNA and RNA Success Criteria _______Can accurately identify the key structural components of DNA (deoxyribose sugar, phosphate group, nitrogenous bases: adenine, thymine, cytosine, guanine). _______Can identify the key structural components of RNA (ribose sugar, phosphate group, nitrogenous bases: adenine, uracil, cytosine, guanine). _______Can describe the differences in the sugar backbone of DNA and RNA (deoxyribose vs. ribose). _______Can identify the double-stranded structure of DNA and the single-stranded structure of RNA. _______Identify the parts of protein synthesis and the location of each process Success Criteria _______Can identify and describe the two main processes of protein synthesis: transcription and translation. _______Can correctly explain that transcription occurs in the nucleus where DNA is transcribed into mRNA. _______Can explain that translation occurs in the cytoplasm at ribosomes where mRNA is translated into amino acid sequences to form proteins. _______Compare and Contrast DNA to RNA Success Criteria _______Can clearly identify similarities between DNA and RNA, such as both being nucleic acids and containing nucleotide structures. _______Can explain differences in DNA and RNA, including sugar types (deoxyribose vs. ribose), strand number (double-stranded DNA vs. single-stranded RNA), and nitrogenous base usage (thymine in DNA vs. uracil in RNA). _______Can describe the function of DNA as genetic storage and the function of RNA in protein synthesis (mRNA, tRNA, rRNA). _______Analyze the reasoning for enzymes usage in both DNA replication and protein synthesis. Success Criteria _______Can identify key enzymes involved in DNA replication (e.g., helicase, DNA polymerase, ligase) and explain their functions (e.g., helicase-unwinding DNA, DNA polymerase-synthesizing new DNA strands, ligase-sealing nicks in the DNA backbone). _______Can identify enzymes involved in protein synthesis (e.g., RNA polymerase) and explain their role in transcribing DNA into mRNA. _______Can analyze why enzymes are essential for speeding up chemical reactions…(ensuring accuracy, and catalyzing steps in replication and protein synthesis) _______Can provide specific examples of how enzyme malfunction can impact genetic replication or protein synthesis. _______Perform the steps of DNA replication and protein synthesis in order to demonstrate their understanding of how the structure of DNA supports the genetic expression in successive generations. Success Criteria _______Can demonstrate a step-by-step understanding of DNA replication, including unwinding, complementary base pairing, and proofreading. _______Can demonstrate the steps of transcription (formation of mRNA from DNA) and translation (conversion of mRNA into a polypeptide). _______Can show how DNA's structure (double helix, base pairing) ensures accurate replication for passing genetic information to offspring. _______Can illustrate how changes in DNA sequence can lead to changes in protein structure and function, thus affecting traits in successive generations.Compare the number of objects in two sets or difference between two measures.Compare the structure of problems with one or two unknownscompare "the work you do, the person you are" and "Drowning in dishes but finding a home"Explain how to compare the area of different shapes5.8.D Identify & Compare The Physical Characteristics Of The Sun, Earth And MoonEstimate and compare the duration of events and tasks
