Water
What are cells made of?
7
Water makes up over 70% of a cell's volume and is essential for life.
Why is water so special?
Water surrounds cells and helps keep a stable temperature within your body (i.e. it maintains homeostasis!)
Insulation
Water is an ideal solvent (something that dissolves other substances). It helps substances travel in and out of the cell.
Solvent
A water molecule has a unique structure with both positive and negative areas. Since it has both, it can attract both positive and negative substances.
BUT HOW?
