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:

Starch and cellulose both are polysaccharides and their monomer unit is glucose sugar. But, starch is an alpha polymer of glucose while cellulose is a beta polymer of glucose.

The excess glucose in plants is stored in the form of starch in various body parts so that it could be used later as an energy source. Starch can be easily broken down to get glucose with the help of enzymes like alpha salivary amylase. Cellulose on the other hand serves the function of structural support and protection because it is very rigid. In plants, cellulose is found in abundance in the cell wall. Most of the animals are incapable of breaking down cellulose because in cellulose, the glucose monomers are joined with each other with the help of β (1 → 4) linkage and these animals lack enzymes which can break β linkage.

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

explanation:

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
