Final answer:
Cellulose and starch are examples of polysaccharides, which consist of long chains of monosaccharides. Cellulose provides structural support for plants, while starch is an energy storage form. Humans can digest starch but not cellulose, which nonetheless has dietary benefits as fiber. (opotion c)
Step-by-step explanation:
Cellulose and starch are both polysaccharides, which means they are made up of long chains of monosaccharides linked together. This makes answer choice "d. polysaccharides" the correct answer to the question: Cellulose and starch are examples of what type of carbohydrates?
Cellulose is a major component in plant cell walls and is composed of many glucose units linked together, forming a linear chain. It provides structural support for plants. On the other hand, starch is also made of glucose units, but it has a slightly different structure, with some chains being branched. Starch is the primary form in which plants store energy.
Furthermore, both cellulose and starch are essential in the diet of humans and other animals. Although humans cannot digest cellulose, it serves as dietary fiber that aids in digestive health. Starch, being digestible, is a significant source of energy in human diets.
Hence, the answer is option c
