Question

Part A:

Answer 1

Answer:

Part A

i) A property of water that contributes to its movement through capillary tubes is adhesion, which is the capacity of water to stick to other surfaces

ii) Water has a polar molecular structure as such the hydrogen present in the water molecules form bonds with the oxygen present in the silicon oxide molecules from which the capillary tube is normally made

Part B.

i) From the given graph, the function appears to have a vertical asymptote at x = 0, therefore, the plant can grow infinitely tall

ii) The molecular structure of the vessel can be modified such that the walls incorporate more oxygen molecules per mole which will increase the number and the strength of the hydrogen bond between the water molecules and the walls of the plant vessel and therefore, increase the capillary action, the water height and the maximum height of the tree
