Question

how does starch compare to cellulose? complete the sentences. plants use cellulose for . they use starch, such as amylopectin, for . unlike cellulose, the long chains of glucose in amylopectin form .

Explanation:

1. For the first blank: Cellulose is a major component of plant cell walls, providing structural support. So plants use cellulose for structural support (or forming cell walls).
2. For the second blank: Starch (like amylopectin) is a storage polysaccharide in plants. So they use starch for storing energy (or energy storage).
3. For the third blank: From the diagram, amylopectin (starch) has branched chains (as seen in the "branched starch" illustration), while cellulose has linear, unbranched chains that form fibers. So unlike cellulose, the long chains of glucose in amylopectin form branched structures (or branches).

Answer:

1. Plants use cellulose for \boxed{structural support (or forming cell walls)}.
2. They use starch, such as amylopectin, for \boxed{storing energy (or energy storage)}.
3. Unlike cellulose, the long chains of glucose in amylopectin form \boxed{branched structures (or branches)}.
