Question

the models show the structures of the carbohydrates cellulose, starch, and glycogen.
cellulose branched starch glyco
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. Analyze each statement:

• "The parallel chains in cellulose give cellulose its strength and rigidity." : Cellulose has linear, parallel chains held by hydrogen bonds, providing structural strength (e.g., in plant cell walls). This is true.
• "Starch, cellulose, and glycogen are monosaccharides." : These are polysaccharides (polymers of monosaccharides like glucose), not monosaccharides. This is false.
• "Cellulose and starch have the same function in plant cells." : Starch is a storage polysaccharide, cellulose is structural (cell wall). Different functions. This is false.
• "Glycogen has more branching than starch." : Glycogen has a highly branched structure compared to starch (starch has less branching). This is true.

1. Identify true statements from the analysis.

Answer:

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