The properties are: (1) Cohesion : mutual attraction between water molecules (2) Adhesion : attraction of water molecules to polar surfaces (3)Surface Tension : water molecules are attracted to each other and give water high tensile strength i.e., an ability to resist a pulling force (4) Capillarity : ability to rise in their tubes. These are also related to the transpiration pull. With this pull water comes to leaves for photosynthesis as well.
