Question

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

Explanation:

1. Cellulose has parallel - chain structure which provides strength and rigidity.
2. Starch, cellulose, and glycogen are polysaccharides, not monosaccharides.
3. Cellulose provides structural support in plant cells while starch is a storage molecule.
4. As shown in the model, glycogen has more branching than starch.

Answer:

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