Final answer:
Sucrose is considered more complex than glucose because it is made up of two different sugar molecules bonded together.
Step-by-step explanation:
Glucose and sucrose are both carbohydrates, but they have different structures and properties. Glucose is a monosaccharide, which means it consists of a single sugar molecule. Sucrose, on the other hand, is a disaccharide composed of two monosaccharides - glucose and fructose - bonded together. In terms of complexity, sucrose is considered more complex than glucose because it is made up of two different sugar molecules.
