3. Learning Objective : Link structure to function in leaves

4. Success Criteria Bronze
Label a diagram of the structure of the leaf. Tabulate structure to function for parts of the leaf.
Silver
Summarise how a leaf is adapted to photosynthesis in terms of obtaining reactants and releasing products.
Gold
Summarise how a leaf is adapted for photosynthesis and suggest how specific leaves/plants are adapted for photosynthesis e.g. rainforest leaves, cacti.

5. Balanced respiration equation Word equation for respiration
Chemical equation for respiration

6. Link adaptations to photosynthesis equation

7. Practical
Paint a thin layer of clear nail varnish onto the underside of the leaf.
Complete the Task whilst you wait for the leaf to dry
After 10 minutes carefully peel off the nail varnish and place on a slide.
Carefully lift the microscope onto the desk by the neck.
Transfer the slide to the microscope.
Move the low power (x4) lens into position.
Move the stage so that it is as close as possible to the lens.
Look down the microscope and bring the nail varnish into focus.
Look for impressions of stomata, guard cells and cells of the lower epidermis
If time, draw a diagram of the guard cells and stomata

8. While the nail varnish is drying.
Task
While the nail varnish is drying.
Come up with a way of representing how each part of the photosynthesis equation is ‘catered for’ by the leaf
Carbon dioxide + water Glucose + oxygen

9. Research
Either complete Q’S
OR Use the laptops to produce a short report on how a specific type of leaf is specially adapted for photosynthesis
e.g. how is a cactus adapted to photosynthesise where there is very little water.
