    1. 1. Cells and reproduction 1P5: Friday 19th November
    2. 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. 3. Nucleus Cytoplasm Cell membrane Animal Cell
    4. 4. Part Function 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.
    5. 5. Nucleus Cytoplasm Cell membrane Vacuole Chloroplast Cell wall
    6. 6. 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
    7. 7. Similarities and Differences BOTH animal and plant cells have ONLY plant cells have: Nucleus Cell wall Cytoplasm Vacuole Cell membrane Chloroplasts The typical plant and animal cells look different to each other – they are different shapes and the nucleus is in a different position.
