The structure of leaves and the use of glucose Lesson aims To study the structure of leaves and how this links to their role in photosynthesis To learn how glucose produced in photosynthesis is used in plants Learning Outcomes By the end of the lesson you should : • know the parts of plant and animal cells and their functions • know how leaf cells close to the upper surface of the leaf are adapted for photosynthesis • know how glucose is used and stored in a plant What did you find out last lesson? Copy: Plant cells have three “extra” things than animal cells: Only plant cells Both types of cell have have these: these: 1) Cytoplasm this is where the reactions happen 2) Nucleus – The “brain” of the cell 3) Cell Membrane – holds the cell together 4) Cell wall – provides support 5) Chloroplasts – contain chlorophyll 6) Large Vacuole – contains sap Copy the diagrams into your exercise book Leaves Read page 66 Connecting science Photosynthesis happens in the “palisade” cells in the leaf: Palisade cells Copy the cross section of a leaf into your books Close up on a palisade cell: Cell wall Cell membrane Large vacuole Chloroplasts (containing chlorophyll) Nucleus Cytoplasm Explain how the palisade cells are adapted for photosynthesis Copy the diagram of a stomata Explain how the stomata are used during photosynthesis (page 66 ) What happens to glucose produced in photosynthesis? Substance What process does a plant use glucose for? made from 2. Copy and complete the glucose table 1. How do you think the substance is used in the plant Learning Outcomes By the end of the lesson do you: • know the parts of plant and animal cells and their functions • know how leaf cells close to the upper surface of the leaf are adapted for photosynthesis • know how glucose is used and stored in a plant
