Oct. 5, 2006 - how plants photosynthesise and what kind of spider is that?!

I think you might appreciate this: We were at a park/playground after a violin concert. Lachlan (5) was on top of the spiderweb equipment "You betta watch out below there’s an enormous red-back down there!" "oooo" go all the other little kids"no wait a minute its not a red back its shelob" "whats a shelob" say all the other kids." (lol!!) My 9yo has asked me how non-green leaf plants like beetroot and some of our basil seedlings photosynthesize? Any ideas?
