Answer: (A)

Verified step by step guidance

1. Step 1: Understand the question. The problem asks to identify which of the given options is NOT the name of a sugar. This requires distinguishing between sugars and other types of biomolecules.
2. Step 2: Recall the definition of sugars. Sugars are carbohydrates, specifically monosaccharides or disaccharides, that serve as energy sources or structural components in living organisms. Examples include glucose, fructose, and galactose.
3. Step 3: Analyze each option. Glucose, fructose, and galactose are all monosaccharides, which are simple sugars. Cellulose, on the other hand, is a polysaccharide, a complex carbohydrate made up of glucose units linked together, and it serves as a structural component in plant cell walls rather than functioning as a sugar.
4. Step 4: Compare the options. Since cellulose is a polysaccharide and not a simple sugar, it does not fit the category of sugars like the other options do.
5. Step 5: Conclude that the correct answer is cellulose, as it is not the name of a sugar but rather a polysaccharide.
