Transcript

  • 1. Cells and reproduction 1P5: Friday 19 th November
  • 2. What are cells?
    • All living things are made of cells
    • A living thing is called an organism
    • Plants and animals are organisms
    • Cells are like the ‘Lego bricks’ – they are the building blocks of life – small units that make up larger structures
    • We’re going to look at Animal and Plant cells
  • 3. Animal Cells
  • 4.  
  • 5. Animal Cell Nucleus Cytoplasm Cell membrane
  • 6. Nucleus Cytoplasm Cell Membrane Controls all cell activities Liquid centre of a cell where chemical reactions happen. The border of a cell which controls what goes in and out of the cell. It only allows small molecules to pass through it and so is known as semi-permeable . Part Function
  • 7. Plant cells
  • 8.  
  • 9. Nucleus Cytoplasm Cell membrane Vacuole Chloroplast Cell wall
  • 10. Part of Cell Function Nucleus Cytoplasm Cell membrane Vacuole Contains a watery liquid called cell sap Chloroplast Contain a green chemical – chlorophyll – responsible for photosynthesis Cell wall Provides strength and support and helps to maintain shape Controls all cell activities Liquid centre of a cell where chemical reactions happen. The border of a cell which controls what goes in and out of the cell
  • 11. Similarities and Differences The typical plant and animal cells look different to each other – they are different shapes and the nucleus is in a different position. BOTH animal and plant cells have ONLY plant cells have: Nucleus Cell wall Cytoplasm Vacuole Cell membrane Chloroplasts
