Take a screenshot of each molecule. Compare the structure of two
of these monosaccharides in a Venn diagram . Just like for other
graphic organizers, the comparison should: be meaningful; be
well-organized and easy-to-follow; show your understanding of the
vocabulary. Be sure to check the rubric before submitting your
work. Share the screenshots of your molecules and your Venn diagram
with your teacher.
