which of the following statements describes ways cellulose and starch are similar to and different from each other?
cellulose and starch are used for structural support in animals, but not plants.
cellulose and starch are both made up of glucose monomers, and cellulose is used as the primary source of energy in animals.
starch and cellulose are both monosaccharides, but starch is used for protection while cellulose is used for transport.
starch and cellulose are both polysaccharides, and most animals can break down starch for energy but not cellulose.

Starch and cellulose are both polysaccharides, and most animals can break down starch for energy but not cellulose.

Explanation:

The reason cellulose is hard to metabolize by most animals for energy is due to the beta acetal linkages of its glucose monomers. This makes these linkages inaccessible to many energy enzymes that hydrolyze glycosidic. These enzymes break down alpha linkages such as those in starch.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
