Answer
Amylose, cellulose, and amylopectin are examples of polysaccharides.
Solution
Polysaccharides are large carbohydrate molecules composed of long chains of monosaccharide units. The examples provided are:
• Amylose (a component of starch)
• Cellulose
• Amylopectin (another component of starch)
Sucrose and lactose are disaccharides, not polysaccharides.

Amylose and amylopectin are both examples of polysaccharides; they are polymeric forms of glucose that serve as energy storage in plants. While amylose is typically linear and forms helical structures, amylopectin is highly branched, making it more soluble and accessible for enzymatic breakdown. Cellulose is another example of a polysaccharide, known for making up the structural component of plant cell walls. Its linear chains of glucose molecules are linked by β(1→4) glycosidic bonds, giving it a robust, fibrous structure that's important for plant rigidity and a dietary source of fiber for many animals.
