Biology Chapter 1 – Cell Biology – eukaryotic and prokaryotic cells Sketch and label a eukaryotic cell for an animal and plant. List at least 3 difference between a light, TEM (transmission electron microscope) and a SEM (scanning electron microscope) microscope? Sketch and label a prokaryotic cell. Draw and label 2 specialised cells and describe the function of these adaptations. State what cell differentiation is. Describe the differences between an eukaryotic cell and a prokaryota cell. What structures are we able to view from a light microscope? What extra structures can we view by using an electron microscope? Explain the function of: Nucleus – Cell membrane – Cytoplasm – Cell wall – Chloroplast – Vacuole – What is a tissue? What is an organ? What is an organ system? Explain how a SEM works compared to a TEM. Explain the structures found in Archaean's and give an example of one type. What are the 3 domains?

Biology Chapter 1 – Cell Biology – mitosis, meiosis, stem cells and cancer Where is our genetic information found? Chromosomes are made of long strands of what? Small sections of this are called what? Human cells contain how many chromosomes? Human cells contain how many pairs of chromosomes? Describe what mitosis is and why it is needed. Describe what happens during mitosis to the chromosomes. Describe what stem cells are. Where are stem cells found? Describe the uses of stem cells. Explain what therapeutic cloning is and explain why we would use it. You may draw a picture if it is easier. State what cancer is. Describe the two different types of tumour and give some characteristic of them. State what triggers cancer. What are the issues with stem cell transplants and how can we resolve them? What is the difference between a moral and ethical concern? Give one scientific, ethical and social issue that may arise from using stem cells. Describe what happens at each stage during the cell cycle. Describe what meiosis is and why it is needed.

Biology Chapter 1 – Cell Biology – maths skills, required practical and aerobic & anaerobic respiration Why do we need energy? Write the word and balanced symbol equation for aerobic respiration. What type of reaction is aerobic respiration? Write the equation to calculate the magnification of an image. Describe a method used to view the structures of an onion cell under a light microscope. Include a risk assessment. Independent variable – Dependent variable – Control variables - Calculate the total magnification: Magnification of the eyepiece is x15 and the objective lens has a magnification of x40. Draw an image and label the parts you can see of an onion cell under a microscope. Write the word and balanced symbol equation for anaerobic respiration. Describe what is fermentation is. Write the word equation for fermentation. Write the equation to calculate the magnification of an image. State why iodine is added to the cell before you look at it under the microscope? Complete the table below with the measurements, some answers require standard form: Calculate the magnification of an image: Micrograph of a plant cell in a book is 175 mm long. In real life the cell measures 120 μm. m cm mm µm nm 1 1000 1,000,000,000 1 x10-4 1 x103 1 x10-2 1 x104 Write and covert these numbers from and to standard form: 100 e. 5.9 x 104 5000 f. 6 x 10-3 3/100 g. 7.8 x 102 1/10000 h. 9 x 10-5
