I was looking at plants and I kept asking myself the question how does the water that the roots get in the ground travel all the way to the leaves since water can’t flow upwards. Then I looked at it under my foldscope and saw that the travels up by something that acts like a paper towel. If you were   to fill a jar with water and place a paper towel in it, the water would spread to all parts of the paper towel and that is how it seemed to work with the plant, the water “stuck” to thes e strands the lead to all over the plant.
