Seeds Contain Dense Aggregates of Starch

question 30

Multiple Choice

Seeds contain dense aggregates of starch.What role does water play in how the seeds use the stored starch?

• A) Water is needed to break the hydrogen bonds in the starch aggregates,allowing ready access to stored energy.
• B) Water is needed to break the peptide bonds in the starch polymers,releasing more water for the plant's use.
• C) Water is needed to activate enzymes that will dissolve the starch into its disaccharide monomers that are used for growth.
• D) Water is needed to dissolve the starch so that it can mix with fats and create new energy compounds utilized by the growing plant.
• E) Water is needed to help transport starch across membranes,allowing communication between the newly growing plant cells.
