ok, Here's an essay question from an old Human bio 08 paper.
discuss 'The biological importance of plants to humans.'
I'm gonna put my essay plan up, can ppl add topics/points to it that I haven't thought of? Breadth is a bit of a problem for me, I can't really 'think outside the box' very well!
Plan:
-plants used in photosynthesis which gives humans glucose (and then a brief description of the stages of photosynthesis)
-so we can respire (brief respiration description)
-needed for ATP. uses of ATP: metabolism, reactions, active transport, e.g. in muscle contractions (brief description of its role in moving calcium ions)
I'm not sure whether these points are relevant for 'biological importance'. What does that even mean???!!!
-Plants, when prevented for decay, gives fossil fuels
-the nitrogen cycle (the leguminous plants) which give us ammonium ions
I'm a bit stuck now. plus it says 'biological' -so can we even talk about fossil fuels?
