Why can the complex sugar cellulose store more energy that the sugar glucose

Because they contain less "built-in" water.

Explanation:

When two glucose molecules 'decide' to bond, they lose a molecule of water:

<span>2<span>C6</span><span>H12</span><span>O6</span>→<span>C12</span><span>H22</span><span>O11</span>+<span>H2</span>O</span>
