Question

What do glucose, starch, and cellulose have in common? (multiple choice answer)

Answer 1

The correct answers are ‘they are various forms of sugar’, ‘they are all carbohydrates’ and ‘they are all related to photosynthesis’. For example, during photosynthesis, plants make glucose, which is converted into starch and used to make cellulose.

Answer 2

The right answer is A and C.

Glucose (of formula C6H12O6) is a simple sugar, also called monosaccharide, present naturally in the body, but is also a constituent of disaccharides and polysaccharides (associated with other sugars to form, for example, sucrose, or several glucoses associated as cellulose).

Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans.
