A base is a substance containing (OH)- group (hydroxide group) in its formula. This means that when a base is dissociated in water, hydroxide group (OH)- will be released in the water which leads to the decrease in the concentration of the hydrogen and increases the pH.

On the other hand, an acid contains H+ in its formula. This means that when acid dissociates in water, hydrogen is releases, thus, increasing hydrogen concentration and decreasing pH value.

<h3><u>Answer;</u></h3>

Cellulose

<h3><u>Explanation</u>;</h3>

Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.

<em><u>It is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
<em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very strong.</u></em>
The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.
