The question asks: 'Starch and cellulose are alike in that both are:'

Because the options are not provided in the input, I cannot enumerate and compare each specific choice. However, we can analyze the fundamental commonality between starch and cellulose.

Key concept: both starch and cellulose are polysaccharides composed of glucose monomers linked together by covalent glycosidic bonds. This shared feature is what makes them similar at a basic chemical level.

Elaboration for the presented option (d): 'Composed of covalently bonded glucose molecules' - This statement is true for both starch and cellulose. In both polymers, the glucose units are joined by glycosidic linkages, though the type of linkage differs (starch typically has alpha-1,4 and branching alpha-1,6 bonds in amylopectin; cellulose has beta-1,4 linkages). The covalent bonds between glucose monomers are the defining connection in these polymers, so the statement accurately captures their common chemical backbone.

If other typical options were present, some common incorrect choices and why they’re misleading might include:
- 'Composed of fructose molecules' would be false because these polymers are built from glucose, not fructose.
- 'Made of amino acids' would be false because starch and cellulose are carbohydrates, not proteins.
- 'Dissolve readily in water' is misleading: starch can form a gel or suspension but is not truly soluble in water, and cellulose is largely insoluble in water; so this would be an inaccurate generalization.
- 'Can be digested by humans' would be partly wrong or misleading: starch is digestible by humans (amylases break it down), whereas cellulose is not digestible by humans due to lack of cellulase, highlighting a difference rather than a similarity.

In summary, the true shared characteristic is their composition from glucose units connected by covalent bonds, which aligns with the provided option (d).
