Verified step by step guidance

Understand the question: The problem asks which biological polymer is made up of simple monosaccharides joined together. Monosaccharides are the simplest form of carbohydrates, such as glucose, fructose, and galactose.

Review the options: The options provided are Triglyceride, Nucleic acid, Polypeptide, and Polysaccharide. Each of these represents a different type of biological macromolecule.

Analyze the structure of each option: Triglycerides are lipids made of glycerol and fatty acids, not monosaccharides. Nucleic acids (DNA and RNA) are polymers of nucleotides, which consist of a sugar, phosphate group, and nitrogenous base. Polypeptides are chains of amino acids, not sugars.

Define polysaccharides: Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Examples include starch, glycogen, and cellulose, which are all carbohydrate polymers.

Conclude: Based on the analysis, the correct answer is Polysaccharide, as it is the only polymer composed of monosaccharides joined together.
