Verified step by step guidance

Understand the question: The problem asks for a type of carbohydrate produced by plants that is not branched. This requires knowledge of carbohydrate structure and function.

Review the options: Chitin, Amylopectin, Glycogen, and Cellulose. Identify which of these are carbohydrates and their structural characteristics.

Recall that cellulose is a polysaccharide produced by plants, composed of β-D-glucose units linked by β-1,4-glycosidic bonds. It forms long, unbranched chains that are used for structural support in plant cell walls.

Compare cellulose to the other options: Chitin is a structural polysaccharide found in fungi and arthropods, Amylopectin is a branched polysaccharide found in starch, and Glycogen is a highly branched polysaccharide used for energy storage in animals.

Conclude that cellulose is the correct answer because it is produced by plants and is not branched, unlike Amylopectin and Glycogen.
