I was counting the number of Carbons, Hydrogen, and Oxygens on Glucose a and b and I found that there were C6H12O6 so I assumed that the Polysaccharides in glucose ring structures are Carbohydrates because they fit a Cn(H20)n chemical formula...

I would not call glucose a hydrocarbon.  I would only use that term to refer to something that had only carbons and hydrogens.

I wouldn't call it a hydrocarbon either, but I always thought that the Cellulose and plant wall structures we composed mainly of Hydrocarbons, because in biology they call them STARCHES(and because starches are mainly formed of C_xH_y I assumed that was true, But from the image I attached you see that there are C_n(H₂O)_n atoms in the structural formula of the glucose a and b Monosaccharides that are really attached as Polysaccharides...
So does that mean that the molecule is a CarboHydrate? or does the molecule have to be a certain combination of Carbons with water?

starches are mainly formed of C_xH_y

Nope.

Let me give you a quick answer now, and perhaps I can tie up any loose ends later.  One, starch and cellulose are both polymers of glucose; therefore, they are isomers of each other.  The chief (but not the only) difference is in the stereochemistry of the acetal bond that connects C-1 of one glucosyl group to C-4 of another.  Two, starch is definitely not a hydrocarbon and it is a storage polymer, whereas cellulose is the main component of plant cell walls.

Three, it is a necessary (but not a sufficient) condition of a molecule to have the formula C_n(H₂O)_n to be a monosaccharide.  But polysaccharides do not conform exactly to this formula, because they lose one water for each acetal bond they form.  Metzler defines a carbohydrate as being either a mono- or a polysaccharide, and that works for me.

I will also not call it as hydrocarbon.They are monosaccharides and are the basic units of many polysacchrides .Alpha and beta glucoses are the stereoisomers and are Diastereomers.
