Really need help!
The two critical properties of water in moving through xylem are cohesion and adhesion. Cohesion allows water molecules to stick together, forming a continuous column of water in the xylem. Adhesion allows water molecules to stick to the walls of the xylem cells, helping to counteract the pull of gravity and enabling water to be transported upward in plants.
A hydrogen bond between the oxygen of one water molecule and the hydrogen of another water molecule.
Adhesion is the attraction between two molecules of different substances.cohesion is the attraction between molecules of the same substances.
cohesion-- Water molecules stick to each other. adhesion-- Water molecules stick to other molecules. Water is a polar molecule because of oxygen is more electronegative. Hydrogen bonds create surface tension and result it water's cohesive and adhesive properties. Hydrophobic = repel water Hydropholic = affinity for water. ...... hahaha XD
Hydrogen bonds between the Oxygen of one molecule and the hydrogen of another :)
its all polar. The molecules are made up of two hydrogen and one oxygen molecule. They arrange themselves in a assymetrical way. This causes the molecule to have a different charge at one end than the other, so the molecules are attracted to one another. That's the short answer, depending on how specific you need there is probably and really specific definition on wikipedia, just read about the physical properties of the water molecule, it is a quite interesting and unique molecule.Also called cohesion.

Adhesion and cohesion are physical properties of water that are caused by water's polarity. This, in turn, is caused by the shape of the water molecule, which forms a partial difference in charge across the length of that molecule, causing intermolecular attractions between water molecules. It also explains surface tension, the fact that water expands when it freezes, and 6-sided snowflakes.

Information used from Prentice Hall Biology book from the year 2006. Cohesion is the attraction between molecules of the same substance. Due to hydrogen bonding water is very cohesive. Water's cohesion causes molecules on the surface of the water to be drawn inward causing "surface tension". This property allows insects to walk on water. Adhesion is the attraction between molecules of different substances. Adhesion causes water to rise in a narrow tube against the force of gravity for example the forces that draw water out of the roots of the plants and up into its stems and leaves, this is called capillarity.
A hydrogen bond between the oxygen of one water molecule and the hydrogen of another water molecule.
In chemistry and physics, cohesion refers to the sticking together of alike molecules, such as water molecule being attracted to another water molecule. Cohesion also causes water molecules to form drops.Together with adhesion It helps to explain the occurrence of surface tension and capillary action.In botany, cohesion pertains to the fusion of plant parts, such as in syncarpy.

well Cohesion- water molecules are attracted to other water molecules. The oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen form other water molecules.This attractive force is what gives water its cohesice properties. And Surface tension- Surface tension is the name we give to the cohesion of water molecules at the furface of a body of water. The cohesion of water molecules forms a surface "film" or "skin ." Some substances may reduce the cohesive force of water, which will reduce the strength of the surface "skin of the water

Hydrogen bonds are what give water its amazing abilities of cohesion, adhesion, and surface tension. Cohesion is what makes water molecules stick together. Think about watching raindrops trickle down a window. When they touch each other, they combine into one droplet. That is the hydrogen part of a water molecule forming a bond with the oxygen part of another water molecule. Adhesion is what allows water molecules to stick to other substances, due to the aforementioned hydrogen bonds. Surface tension is what allows some insects to walk on water. If you look closely at them, you can see the surface of the water dip where the insects' legs touch the water. The water molecules are still being held together by the hydrogen bonds; however, if you or I were to try to walk on water, our weight would cause the hydrogen bonds to break, and we would fall in.
When water molecules are attracted to other water molecules, this is called COHESION. This is because the oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from the other water molecules. This is what causes Cohesion. :)
