What a fantastic result B- had investigating the movement of water in a plant! He stood the stem of a white flower in coloured (yellow) water and after 2 hours the petals had turned yellow! How did the white flowers change colour? B has drawn a picture to show us. Do you know what the tiny tubes inside the stem are called that take the water up? Do you know how the water is pulled up the stem? If you do, then let us know! Well done B, some great science!
