A level bio 20marker

Hello, does anyone have any tips on writing 20mark biology questions? The question i have to answer is ‘describe the roles of water in living organisms and as an environment for living organisms’. Is there any specific pieces of info or a way to structure that will get you high marks (what im aiming for). Thanks! (Cie exam board)
Sorry you've not had any responses about this. :frown: Are you sure you've posted in the right place? :smile: Here's a link to our subject forum which should help get you more responses if you post there. :redface:

Hey just curious were you tasked to write this 20 marker? Pretty sure CIE A level Biology removed 20 markers from the exam

I guess you can talk about water being a solvent, a metabolite, high shc, latent heat of vaporisation and cohesion. And then you can bring in stuff about the xylem and phloem - process of transpiration and translocation. Maybe then talk about water being used in photosynthesis and respiration.
