2e) Plant Nutrition
2.17 describe the process of photosynthesis and understand its importance in the conversion of light energy to chemical energy 2.18 write the word equation and the balanced chemical symbol equation for photosynthesis 2.19 understand how varying carbon dioxide concentration, light intensity and temperature affect the rate of photosynthesis 2.20 describe the structure of the leaf and explain how it is adapted for photosynthesis 2.21 understand that plants require mineral ions for growth and that magnesium ions are needed for chlorophyll and nitrate ions are needed for amino acids 2.22 describe experiments to investigate photosynthesis, showing the evolution of oxygen from a water plant, the production of starch and the requirements of light, carbon dioxide and chlorophyll

 * Approach **

A good introduction to photosynthesis by GCSE Science Revision
 * Tutorials**

A [|good video tutorial from skoool.co.uk] covering all the aspects of photosynthesis you need to understand. Hold your cursor over the numbers on the right to quickly access the sub-topic you want to review.

A simple, but useful, [|revision tutorial from s-cool] with an overview of photosynthesis.

 * Activitiy suggestions**

__Marketplace__ There will be different three groups
 * The importance of photosynthesis and it's equations (2.17, 2.18)
 * How does sunlight carbon dioxide and temperature affect photosynthesis? (2.19)
 * Explain how leaf structure is adapted for photosynthesis (2.20)

The research - each group will have 30 mins to research and learn about their area of knowledge using the resources listed above under tutorials. You need to develop:
 * A teaching aid (containing no more than 12 words)
 * Notes to refer to when teaching others

The market place - four rotations of 6 minutes each:
 * One person will stay and teach people from other groups
 * Other members of the group will take note paper and learn from the other groups

Teach the teacher:
 * return to your group
 * the teacher now becomes the scribe and you will work together to complete your workbook using the notes you have collected


 * Labs and practical work**

Simulated photosynthesis labs
 * [|Biology Corner] has a good outline and link to a photosynthesis simulation (from [|Saddleworth school])
 * Reading University has a good [|online simulator] for photosynthesis, but the independent variable is restricted to light intensity

Testing leaves for starch You should be able to outline this process and also be able to interpret the results. Follow the steps and answer the questions.

Plants use many different strategies to obtain nutrients and their structures consequently are hugely varied. Puya chilensis, a native of Chile, is adapted to trap and eat sheep!
