Question

Starch is an example of _______.

• A. Monosaccharides
• B. Oligosaccharides
• C. Disaccharides
• D. Polysaccharides

Answer 1

The Correct Option is D

The correct answer is (4) Polysaccharides.

Starch is a polysaccharide, which is a type of carbohydrate made up of many glucose molecules linked together in a chain. Polysaccharides are complex carbohydrates, and starch is a primary storage form of energy in plants.

Let’s review the other options:

(1) Monosaccharides: Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar unit. Examples include glucose, fructose, and galactose.

(2) Oligosaccharides: Oligosaccharides are carbohydrates composed of 2-10 monosaccharide units. Examples include maltodextrins and some sugar chains.

(3) Disaccharides: Disaccharides are carbohydrates made of two monosaccharide units. Examples include sucrose (table sugar), lactose (milk sugar), and maltose (malt sugar).

Thus, starch is a polysaccharide because it is made up of many glucose units, making the correct answer (4) Polysaccharides.

Answer 2

Starch is a complex carbohydrate made up of numerous glucose units linked together. It is classified as a polysaccharide and serves as a primary energy storage molecule in plants.
