1 Limiting Factors in Photosynthesis
IGCSE Combined Science

2 Group work – concept cartoons!

3 Rate of photosynthesis

4 Now have a look at the demonstration of Elodea!
Try and answer the following questions as you are given the demonstration What are the effects of changing: Carbon dioxide concentration Temperature Light intensity Be able to give a scientific explanation for each of these factors as well!

5 What happens when we change these factors?

6 Rate of photosynthesis

7 Group activity! Can you make a poster summarising the effect of changing Light intensity Carbon dioxide concentration Temperature Your poster must include a sketch graph for each three factors and an explanation of why they affect the rate of photosynthesis!

8 finished photosynthesis!
YAAAAY!! We´ve finished photosynthesis! Copy and complete the following sentences based on your OVERALL understanding of the photosynthesis topic so far... Something I have enjoyed learning is... Something I find difficult is... An example of a test question could be...
