  1. What are all living things made of?

  2. Cells Animal

  3. What do you already know about cells? Are there any words you associate with cells?

  4. What is a cell? http://bit.ly/dOAsO6

  5. 1 Eye-piece 2 Optic tube 4 3 Arm Objective lens 5 6 Stage Focus control 7 Light 8 Base Always carry a microscope holding the arm 9

  6. Animal Cell Slide • Place a drop of methylene blue on your slide • Rub the inside of your cheek with a cotton swab then rub it on your slide • Place your swab in disinfectant. DO NOT put in on the table • Carefully lower a cover slip over the sample, use a pencil to help you • Make sure you have no air bubbles

  7. Scientific Drawing Make a scientific drawing of an animal cell. Rules of scientific drawings: • Use only straight lines • Do not colour or shade in • Label each part with a straight line. No arrow head

  8. Animal Cell • Write the title Animal Cell in your jotter • Copy the animal cell diagram below Cell Membrane Nucleus Cytoplasm

  10. Cells Plant

  11. Plant Cell Slide • Peal off a thin layer of onion tissue and place on a slide • Carefully spread the piece of tissue out so that there are no folds • Place a couple of drops of iodine on the onion tissue • Carefully lower a cover slip over the sample, use a pencil to help you • Make sure you have no air bubbles

  12. Scientific Drawing Make a scientific drawing of a plant cell. Rules of scientific drawings: • Use only straight lines • Do not colour or shade in • Label each part with a straight line. No arrow head

  13. Plant Cell • Write the title Plant Cell in your jotter • Copy the animal cell diagram below Chloroplast Vacuole Cell Membrane Nucleus Cell Wall Cytoplasm

  14. Cell structure and function Each part of a cell has its on role to play in the working of it. Using the cards match each cell structure to its function. (you have 2 minutes)

  15.  The control centre of a cell. This controls what substances can enter and leave the cell.   The jelly like filling of a cell. This is where chemical reactions take place in a cell.    The rigid firm coating found around a plant cell. It helps to keep the cell shape.   Contain a green chemical called chlorophyll which absorbs sunlight. Allow plants to make their own food.  Can store sugar and water. Helps to control the water content of plant cells  

  16. Cells Variety

  17. Plant or Animal cell? Why? ? Animal Cell Plant Cell A is a ? cell B is a ? cell

  18. Plant or Animal cell? ? A Vacuole Cell Wall B C Chloroplast Cell Membrane D Nucleus E Cytoplasm F Animal Cell Plant Cell

  19. Animal, Plant and Microbial Cells Animal CellPlant CellMicrobial Cells Similarities and Differences?

  20. In your jotter… Microbial cells do not have a nucleus. Examples of microbes Bacteria: Lactobacillus, E. coli Microbial Cells

  21. Some cells are specialised for a particular job.Below are pictures of plant, animal and bacterial cells.They all look different because they have different jobs to do.

  22. Can you think of reasons why they look this way? Bacterial cell Root cell Sperm cell Windpipe cell Leaf cell Blood cell Pollen cell Nerve cell

  23. How big are cells? Arrange the pictures in order from biggest to smallest…

  24. Biggest • Coffee bean • Grain of salt • Amoeba • Paramecium • Human egg cell • Skin cell • Red blood cell • Sperm cell • Bakers yeast • E. coli • Influenza virus • Carbon atom Smallest

  25. Plant, Animal or Microbial Cell?Write your answer on a whiteboardYou should be prepared to explain your answer

  29. Cells 3D Model

  30. Challenge Your challenge is, in pairs, to create a 3D model of a cell using the materials provided. Paper Glue Plastic tubs Pens Balloons Card (different colours) Jelly Sandwich bags (medium/small) Peas Foam Paper plates (big/small) Sponges Marbles Bubble wrap Lollypop sticks Once all models are complete you will each take turns going round looking at each others and giving feedback.

  31. Some ideas

  32. First, plan your 3D cell model. You may look at the materials available, but ask first if you want out your seat. Paper Glue Plastic tubs Pens Balloons Card (different colours) Jelly Sandwich bags (medium/small) Peas Foam Paper plates (big/small) Sponges Marbles Bubble wrap Lollypop sticks You may not start building your model until I have seen your plan.
