How many sugar units make up monosaccharides?
A
one
B
two
C
three
D
zero
Explanation: 

Detailed explanation-1: -Monosaccharides consist of a single sugar. Examples include glucose and fructose. Depending on the number of carbon atoms, the carbohydrate may be a triose, tetrose, pentose or hexose. Disaccharides contain two sugar units.

Detailed explanation-2: -A saccharide refers to the unit structure of carbohydrates. Thus, a monosaccharide is a carbohydrate comprised of only one saccharide unit. The term sugar can refer to both monosaccharides and disaccharides. Monosaccharides are also called simple sugars since they are the most fundamental type of sugar.

Detailed explanation-3: -Monosaccharides are comprised of a single simple sugar unit, glucose, fructose, or galactose, and they cannot be broken down into simple sugar units. These three monosaccharides are combined in various ways to make more complex carbohydrates. Disaccharides are comprised of two monosaccharides bonded together.

Detailed explanation-4: -Simple sugars contain one or two sugar molecules. A carbohydrate with one sugar molecule is called a monosaccharide, whereas one with two sugar molecules bonded together is a disaccharide.

Detailed explanation-5: -Monosaccharides are the simplest units of carbohydrates and the simplest form of sugar.
