Question

plants also make the polysaccharide starch to store excess glucose. starch is made from many molecules of glucose joined together in long chains. one form of starch, amylopectin, has long chains with several branches.
diagrams of amylopectin structure (starch) and cellulose structure
how does starch compare to cellulose? complete the sentences.
plants use cellulose for dropdown. they use starch, such as amylopectin, for dropdown. unlike cellulose, the long chains of glucose in amylopectin form dropdown.

Explanation:

1. For the first blank: In plants, cellulose is a major component of the cell wall, providing structural support. So plants use cellulose for structural support (or forming cell walls).
2. For the second blank: The text states that plants make starch (like amylopectin) to store excess glucose. So they use starch for storing excess glucose (or energy storage).
3. For the third blank: The diagram shows amylopectin has branched chains, while cellulose has unbranched chains. So the long chains of glucose in amylopectin form branches (or a branched structure).

Answer:

• Plants use cellulose for \boxed{structural support (e.g., forming cell walls)}.
• They use starch, such as amylopectin, for \boxed{storing excess glucose (energy storage)}.
• Unlike cellulose, the long chains of glucose in amylopectin form \boxed{branches (a branched structure)}.
