What is a characteristic of cellulose?

Cellulose is characterized by its crystalline structure, which contributes to its strength and rigidity as a key structural component in plant cell walls. This crystalline arrangement allows cellulose to provide the necessary support for plants to maintain their shape and resist external stresses.

In contrast to the other options, cellulose is not easily hydrolyzed; it resists enzymatic digestion in humans and many other animals due to its β-1,4-glycosidic bonds, making it a challenging carbohydrate to break down. Additionally, cellulose is not a liquid at room temperature; it is a solid, fibrous polymer. Finally, cellulose is primarily found in plant products rather than animal products, being a significant component of dietary fiber.
