What kind of properties does water have?
cohesive properties
Why does water move as one mass?
because the molecules are attraced to each other (because of cohesion)
As it moves as one mass because the molecules are attracted to eachother, this is how plants are able to draw what up?
draw water up from their roots and how you are able to drink water through a straw
What other properties does water also have?
adhesive properties - this is where water molecules are attracted to other materials
For example, when you wash your hands, your hands become wet, and the water doesn’t run straight off. What are the water molecules more strongly cohesive to?
each other than they are to air -> this results in water having a ‘skin’ of surface tension
What are the characteristics and properties of water vital in?
sustaining life
Because water is a polar molecule, what does it act as?
a solvent in which many of the solutes (substances) in an organism can be dissolved
What is the cytosol of prokaryotes and eukaryotes?
mainly water
Many solutes (substances) are also what?
polar molecules, amino acids, proteins, and nucleic acids
What does water act as?
a medium for chemical reactions
What does water help to transport?
dissolved compounds into and out of cells
What does water make a very efficient transport medium for?
within living things
What does cohesion between water molecules mean?
when water is transported through the body, the molecules will stick together
Where does adhesion occur between?
water molecules and other polar molecules and surfaces
What does the effects on adhesion and cohesion result in?
water exhibiting capillary action
