    Okay I am really confused about my Bio extended essay I have gone thru a lot of websites and I think this is a good topic but I need some opinions, pointers, any help, I have time but I want a head start cuz I know I have to collect a lot of data....

    This is the topic:
    Effects of the increasing Co2 on the photosynthesis of (2 plants)

    I was thinking of doing experiments on 2 different plants to also show how the effect varies when the plant species is different

    Have you talked to your teacher about this? Think about feasibility and how many individual plants you'll need to do some stats.
