How does the shape of cellulose make possible its function? Note the arrangement of individual cellulose molecules and bonds as part of your answer and mention something about both covalent and noncovalent bonds. If you really want to see the H bonds, right click on the jsmol figure, choose \"style\" \"hydrogen bonds\" and then set their diameter to 30 Angstroms. You can also choose \"color\" and make them some other color to make them easier to see! Solution Cellulose is the most abundant organic compound on earth. It is a major component of tough cell walls that surround plant cells, and is what makes plant stems, leaves, and branches so strong. Its unique, rigid structure serves an important function in plants. Its molecules are joined together using hydrogen bonds and are arranged parallel to one another, forming a long, cable-like structure that merges with other cellulose molecules. This creates the strong support structure that allows plants to stand upright. Note: Image is missing in the question.
