Covalent
1 of 13
Name 3 uses of water
Transport, removal of waste and secretions
2 of 13
What does polar mean?
An unequal distribution of charge
3 of 13
Why is water polar?
There is a net negative charge on the oxygen ion and a net positive charge on the H ions
4 of 13
What bonds are formed in water?
H2 bonds
5 of 13
How is water used for transport?
In blood plasma, tissue fluid, xylem sap ect. water dissolves many substances allowing easy transportation

What are H2 bonds?
Weak, long distance bonds
7 of 13
What do lots of H2 bonds do?
Holds H2O molecules together, this sticking is called cohesion
