Biology : What are they composed of, and where can they be found, (ex. organisms), and what's their function?

Question

What are the monosacharides that make up the following polysaccharides?
Starch
Glycogen
Cellulose

What organisms or cells contain the above polysaccharides? (please name one organism for each one above.)

And, what function does each of the above polysaccharides have?(please name the functions for each one above.)

THANKYOU!!!!!!!!!!!!!!!!!!!!!

Answer 1

A)glucose
B)potatoes, humans, broccolli
C)They give, and store energy.

Answer 2

Glucose is the monosaccharide that makes up all of the polys. They are simply bonded in defferent ways.

Starch is the storage form of energy for plants (like a potato) while animals (humans) store their energy as glycogen. Cellulose is the compound that makes up plant cells...serves as a sort of 'exoskeleton' for plants. You know what cellulose is...look at a stalk of broccoli and the fibrous stuff at the base is thick and stringy...that's cellulose.
