Cell Biology:

  • Use the terms 'eukaryotic' and 'prokaryotic' to describe types of cells
  • Describe the features of bacterial (prokaryotic) cells
  • Demonstrate an understanding of the scale and size of cells and be able to make order of magnitude calculations, inc standard form
  • Recall the structures found in animal and plant (eukaryotic) cells
  • Describe the functions of the structures in animal and plant (eukaryotic) cells
  • Use estimations and explain when they should be used to judge the relative size or area of sub-cellular structures
  • Required practical 1: use a light microscope to observe, draw and label a selection of plant and animal cells
  • Describe what a specialised cell is, including examples for plants and animals
  • Describe what differentiation is, including differences between animals and plants
  • Define the terms magnification and resolution
  • Compare electron and light microscopes in terms of their magnification and resolution
  • Carry out calculations involving magnification using the formula: magnification = size of image/ size of real object -inc standard form
  • Describe how genetic information is stored in the nucleus of a cell (inc genes & chromosomes)
  • Describe the processes that happen during the cell cycle, including mitosis (inc recognise and describe where mitosis occurs)
  • Describe stem cells, including sources of stem cells in plants and animals and their roles
  • Describe the use of stem cells in the production of plant clones and therapeutic cloning
  • Discuss the potential risks, benefits and issues with using stem cells in medical research/treatments (inc diabetes and paralysis)
  • Describe the levels of organisation within living organisms
  • Describe the structure of the human heart and lungs
  • Explain how the heart moves blood around the body (inc role and position of the aorta, vena cava, pulmonary artery & vein and coronary arteries)
  • Explain how the natural resting heart rate is controlled and how irregularities can be corrected
  • Describe the structure and function of arteries, veins and capillaries
  • Use simple compound measures such as rate and carry out rate calculations for blood flow
  • Describe blood and identify its different components, inc identifying blood cells from photographs/diagrams
  • Describe the functions of blood components, including adaptations to function
  • Describe what happens in respiration including using a word equation and recognise the chemical formulas for carbon dioxide, water, oxygen & glucose
  • Describe aerobic and anaerobic respiration with regard to the need for oxygen, the differing products and the relative amounts of energy transferred
  • Recognise the equations for aerobic respiration, anaerobic respiration in muscles and anaerobic respiration in plants and yeast cells.
  • Recall what type of respiration fermentation is and its economic importance.
  • Describe what happens to heart rate, breathing rate and breath volume during exercise and why these changes occur
  • Explain what happens when muscles do not have enough oxygen and define the term oxygen dept
  • Explain what happens to accumulated lactic acid in the body
  • Explain the importance of sugars, amino acids, fatty acids and glycerol in the synthesis and breakdown of carbohydrates, proteins and lipids
  • Explain what metabolism is, including examples
