A condensation reaction.
What bond is formed during a condensation reaction? 
A glycosidic bond.
What happens when water is added to a disaccharide? 
It breaks the glycosidic bond, releasing the monosaccharide.
What is it called when a glycosidic bond is broken? 
A hydrolysis reaction.
What is a polysaccharide? 
They're polymers formed by combining together many monosaccharides.
Why are monosaccharides bonded to make di& polysaccharides?
To make monosaccharides more suitable for transport, storage and to have less influence on a cell’s osmolarity.
