Homework Help: What are the differences between C3 and C4 plants?

  1. Nov 21, 2011 #1
    Hi, I'm confused about C3 and C4 plants.

    I know that their differences stem from how they photosynthesise differently but I am struggling to see how this relates to their different saturation and light compensation points?

    I know that C4 plants have a higher light saturation point compared to C3- but why?

    and I know that C3 plants have a higher light compensation point compared to C4 but again why- how does this link back to their different abilities to photosynthesise?

    Any help, even just some broad ideas to point me in the right direction- would be greatly appreciated
