Starch is used to store energy and cellulose is a structural polysaccharide. The key differences that explain these functions are:
A. cellulose with high branching aids strong structures, and starch with low branching makes for easy energy release. B. the unbranched structure of starch makes it easy to process for energy, and the branched structure in cellulose creates strong bonds. C. alpha 1-4 and alpha 1-6 glycosidic linkage in starch creates branching, and beta 1-4 in cellulose creates unbranched structures. D. beta 1-4 and alpha 1-6 glycosidic linkage of starch can create branches, and alpha 1-4 linkages in cellulose creates cellulose.

Coleochaete spend their entire life as a haploid organism. In what major way do these algae differ from mosses and flowering plants?
A. They do not undergo alternation of generations. B. They have a more prominent sporophyte generation. C. They do not undergo mitosis. D. They do not undergo photosynthesis.
