macmillanbiologyNSW Year 11Introduction to teacher resourcesPROOFSThese teacher resources act as a supplement to the textbook Macmillan Biology NSW Year 11. Theyprovides lesson plans for teachers and suggests answers for each activity.The Macmillan Biology NSW Year11 textbook and these resources integrate the Australian seniorBiology curriculum into the New South Wales Biology Stage 6 Syllabus (released by the NSWEducation Standards Authority (NESA) in March 2017). This incorporation was based on the rationaleand aims of the Australian senior Biology curriculum, as defined by its learning, content (scienceinquiry skills, science understanding, and science as a human endeavour) and achievement standards(biology concepts, models and applications and biology inquiry skills).Modules 1–4 of the student book are based on the NSW Biology Stage 6 Syllabus. The openingpage of each of module lists the appropriate NSW Biology Stage 6 Syllabus learning outcomes. Theteacher resources align with each of the modules in the student book.Each lesson plan lists the appropriate NSW Biology Stage 6 Syllabus content, coded to show:ECTED module number (1–4) module content topic (listed in order as A, B, C etc.) dot point within module content (listed in order as 1, 2, 3, etc.)For example, code 1B4 represents module 1 (Cells as the basis of life), content topic B (Cellfunction), dot point 4 (conduct a practical investigation to model the action of enzymes in cells(ACSBL050)). The final code in the dot point refers to the relevant part of the Australian seniorBiology curriculum.Lesson plans include:UNCORR Interpreting data—where students analyse and interpret biological data and informationpresented from a variety of sources. Sources include peer-reviewed journal articles in whichscientists record and discuss the results of their research; results from experiments given to studentsfrom 2002 to 2008; some data and information similar to real data Practical investigations (PIs)—directed practical activities and appropriate discussion questions Secondary source investigations (SSIs)—where students are expected to find information froma variety of sources, including Macmillan Biology NSW Year 11, to answer discussion questionsassociated with each activity Evaluating biological issues (EBIs)—where students gather information and evaluate the effectof human interventions on biological systems and how they affect present-day and future society Assessment tasks—including revision tests, practical tests, skills tests and research tasks.Each activity (except for the EBIs) should be completed within 40 minutes to one hour, and insome cases can be continued or used for homework. These lesson plans are designed to be printed outfor the class. Suggested answers to all questions posed in lesson plans are provided.Sections 5–8 of this teacher resource book provide suggested answers to questions posed inMacmillan Biology NSW Year 11. These include: answers to the revision questions (at the end of each of chapters 1–21) Copyright Macmillan Education Australia 2017macmillan biology, NSW Year 11ISBN 978-1-4202-3850-1

Too much carbonic acid is toxic to cells,because it lowers the pH of the cell fluids (that is, they become more acidic) and reduces the efficiencyof enzymes that normally function at less acidic levels. So cells need to remove waste carbon dioxidequickly and efficiently for the body to maintain homeostasis.Similarly, the concentrations of environmental gases in aquatic environments affect the survival offish and invertebrates. Oxygen is fundamental to their basic life processes and carbon dioxide is ananimal waste product (but used by aquatic plants for photosynthesis). When there is an imbalance inthese gases, many organisms die. This situation can be exacerbated in warm weather. Gases that arenormally held in solution in the water may gain enough energy to escape as the water heats up, leavingthe organisms with insufficient oxygen or carbon dioxide to sustain life.RRAimsUNCOHypotheses Copyright Macmillan Education Australia 2017macmillan biology, NSW Year 11ISBN 978-1-4202-3850-1

This occurs naturally in systems,such as gas exchange between the blood and the lungs, so that balance is maintained.Osmosis is a form of diffusion, but only water moves. In osmosis, water follows a concentrationgradient but, unlike normal diffusion, it occurs across a semi-permeable membrane. That is, watermoves from areas of high concentrations of water (dilute solutions) to areas of low water concentration(concentrated solutions). Osmosis is an important process that regulates transpiration in plants—watermoves by osmosis out of leaf mesophyll cells into leaf spaces. Subsequent evaporation and diffusion ofwater vapour out of open stomates creates a negative pressure, which causes water in xylem to bepulled up the plant.CORRECDemonstrating diffusionUNDiffusion in air Copyright Macmillan Education Australia 2017macmillan biology, NSW Year 11ISBN 978-1-4202-3850-1Diffusion in water

macmillanbiologyNSW Year 11FS1.4 Practical investigation: Effect of temperature,pH and substrate concentration on enzymereactionStudents:PROO1B4 conduct a practical investigation to model the action of enzymes in cells (ACSBL050)1B5 investigate the effects of the environment on enzyme activity through the collection of primary orsecondary data (ACSBL050, ACSBL051)IntroductionCOAimRRECTEDEnzymes act as catalysts in chemical reactions and function best at optimal levels of temperature, pHand substrate concentration. Enzymatic activity can be shown to increase or decrease depending onthe environmental conditions. That is, reaction rate will increase with increasing temperature andsubstrate concentration up to a maximum, after which there will no longer be any increase.This is because enzymes rely on temperature to provide energy for the reaction, but enzymes willnot operate when temperatures are too high. Each type of enzyme functions within a range oftemperatures or pH. Above or below the specific optimal temperature or pH function will decrease.And outside this range, enzymes will denature and no longer function. Also, enzyme activity will onlyincrease until all available substrate is used up or all enzyme active sites are occupied.Animal cells (including liver cells) produce an enzyme—catalase—that breaks down harmfulhydrogen peroxide (produced in normal metabolism) into non-toxic oxygen and water (2 H2O2 2H2O O2). Catalase functions at an optimum temperature of 37 C, similar to the temperature of thehuman body.UNHypotheses Copyright Macmillan Education Australia 2017macmillan biology, NSW Year 11ISBN 978-1-4202-3850-1

Compound light microscopes(microscopes that employ the use of more than one lens) were first developed at the end of thesixteenth century by the Dutch lens makers Hans and Zacharias Janssen. It was, however, the realisticillustrations of microscopic observations of organisms by the Englishman Robert Hooke (1635–1703)in his book Micrographia, first published in 1665, that acted as a catalyst for future discoveries. Hookeincluded a diagram of thin slivers of cork from an oak tree, and used the term ‘cell’ for each of thehundreds of pores that made up the cork—but thought that these cells only existed in plants. ADutchman, Anton van Leeuwenhoek was also influenced by Hooke’s Micrographia. Consequently,he made simple microscopes that had a much greater magnification than Hooke’s compoundmicroscope. Therefore, in 1676, Leeuwenhoek was the first to describe living unicellular organismsand bacteria. In 1683, he sent diagrams of bacteria from plaque around his teeth to the Royal Society ofLondon.Science in the seventeenth century focused on observation, description and diagrams. By the1800s, the improved lenses in microscopes, and a more experimental approach to science, contributedto an increased knowledge of the nature of cells. For example, the compound microscope developed byEnglishman Joseph Lister in 1826 had better resolution and clearer images, so he was able to describered blood cells. With this improved technology, Robert Brown, a Scottish botanist, noted in 1831 asmall spherical body in plant cells that he called a nucleus.The popular belief in spontaneous generation hindered advances in cell theory until, in 1859, theFrench chemist Louis Pasteur disproved that theory by showing that microorganisms can only growfrom other microorganisms. In the meantime, the German botanist Matthias Schleiden proposed, in1838, that the nucleus was important in cell development, that all plant tissues are made of cells, andthat each new plant was formed from a single cell. In 1839 his colleague, the German physiologist andhistologist Theodor Schwann, extended the cell theory for plants to animals. That is, Schleiden andSchwann established cells as the basic units of struc
