Question

structures of the carbohydrates cellulose, starch, and glycogen. cellulose branched starch glycogen select the true statements. the parallel chains in cellulose give cellulose its strength and rigidity. glycogen has more branching than starch. cellulose and starch have the same function in plant cells. starch, cellulose, and glycogen are monosaccharides.

Explanation:

1. Cellulose has parallel chains which contribute to its strength and rigidity, making the first statement true.
2. Glycogen is highly - branched compared to starch, which is also true.
3. Cellulose provides structural support in plant cells while starch is a storage molecule, so they have different functions, making the third statement false.
4. Starch, cellulose, and glycogen are polysaccharides (made up of many monosaccharide units), not monosaccharides, making the fourth statement false.

Answer:

The parallel chains in cellulose give cellulose its strength and rigidity.
Glycogen has more branching than starch.
