Plants use polysaccharides such as cellulose for
A
Energy Storage
B
Cell Structure
C
Cell Identification
D
None of the above
Explanation: 

Detailed explanation-1: -Cellulose is the most essential structural component of plant cell walls and the most common macromolecule and organic substance on the Earth. Cellulose is made up of carbohydrates which is a polysaccharide structure. Polysaccharide is made up of long chains of many sugar molecules that are chemically linked together.

Detailed explanation-2: -In the cell walls of higher plants, the tensile fibers are made from the polysaccharide cellulose, the most abundant organic macromolecule on Earth, tightly linked into a network by cross-linking glycans.

Detailed explanation-3: -Cell walls are composed primarily of multiple polysaccharides that can be grouped into three major classes: cellulose, pectins, and hemicelluloses.

Detailed explanation-4: -Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth.
