National 4 and 5 Biology Unit One Cell Biology Success Criteria Level 4/5 4/5 4/5 5 5 5 5 4/5 4/5 4/5 5 5 4/5 4/5 4/5 4/5 5 5 5 4/5 4/5 4/5 5 What I need to be able to do… Cell structure Label an animal cell – Cell membrane, cytoplasm and nucleus Label a plant cell – Cell wall, cell membrane, cytoplasm, nucleus, chloroplast and vacuole State the function of all the parts of animal and plant cells listed above Identify the mitochondria and ribosomes in a cell diagram Explain the function of a mitochondria and a ribosome Label a bacterial cell and explain the differences between it and other types of cell. Label a fungal cell and explain the differences between it and other types of cell. Transport Describe the structure of the cell membrane Explain what happens during diffusion Explain what happens during osmosis Describe the effects of different water concentrations on animal and plant cells Explain the difference between passive and active transport Producing New Cells Describe what happens during mitosis Explain what the chromosome complement is and why it important that it is maintained Explain how mitosis (cell cycle) is controlled and how this can lead to cancer DNA and Protein Production Explain what is meant by DNA, genes and chromosomes Describe structure of a nucleotide State the letters which identify the 4 different bases and how they pair up Explain how the genetic code works Explain the structure of proteins Genetic Engineering Describe the process of genetic engineering List examples of how genetic engineering has been used Describe what is meant by a GM organism and why it might be controversial Covered 4/5 4/5 4/5 4/5 4 4/5 4/5 5 5 5 4/5 5 4 4 4 4/5 4/5 4/5 5 5 4/5 5 4/5 4/5 4 Proteins and Enzymes Explain what enzymes do and what the main features of an enzyme are Give 3 named examples of chemical reactions carried out by enzymes and be able to draw the word equations Explain how temperature effects enzyme activity Explain how pH effects enzyme activity Describe some uses of enzymes in industry e.g. Biological detergents and rennet in cheese making Respiration Explain what cells need energy for Write the word equation for aerobic respiration Explain what ATP is and draw its structure Explain how ATP is produced in the cell and how many ATP are produced for each molecule of glucose Explain what happens during glycolysis Describe what is meant by anaerobic respiration Explain what the products of anaerobic respiration are in humans and yeast Explain how anaerobic respiration can be used to benefit man (fermentation in yeast – breadmaking and brewing) Explain how exercise and training can improve your recovery time Photosynthesis Explain the importance of plants and give examples of the uses of named plants e.g. food, raw materials and medicines Explain the importance of photosynthesis Write the word equation for photosynthesis Describe how to test a leaf for starch Explain what happens in the first stage (light reaction) of photosynthesis Explain what happens in the second stage (carbon fixation) of photosynthesis Label the parts of a leaf Explain the role of the xylem and phloem Explain what a limiting factor is List the limiting factors for photosynthesis Describe how farmers and gardeners control the limiting factors to ensure healthy plant growth
