Glucose, a monosaccharide, is found in three different polysaccharides: starch, glycogen, chitin. there are differences between the structure and function of the glucose arrangement found in these polysaccharides. which statement correctly identifies the difference in glucose structure in one of these polysaccharides?

The statements are not given so we'll just differentiate these 3 polysaccharides:

For starch and glycogen, they are known as storage polysaccharides for plants and animals, respectively. They are similar in terms of the glucose bonds used in the initial arrangement. The glucose isomer has a hydroxyl (-OH) group attached to C1. Amylose and amylopectin are present in glycogen and starch. In contrast, glycogen contains more amylopectin with frequent branching than starch.

The monomers of glucose are linked by 1,4 glycosidic bonds. These links  produce an unbranched polysaccharide which transforms into a helix.

The 2 types of glycosidic bonds in amylopectin are 1,4 and 1,6 glycosidic bonds. Due to the presence of the two bonds, it's now considered as a branched polysaccharide. Glycogen contains more of amylopectin compared to starch.

Chitin is also a polysaccharide made from glucose. It is seen usually in the cell walls of fungi and hard exoskeletons of insects and crustaceans. It is an unbranched polymer made from N-acetyl-d-glucosamine (NAG) linked by beta-glycosidic bond. Recent studies have used chitin as a treatment for osteoarthritis and immunomodulation.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
