<span>The answer is B) cell wall. The cell wall is a structure important cell protection and shape. It is necessary for the survival of unicellular organisms, such as Archaea and bacteria. Plants, some fungi, and algae also have cell walls with major function in structural support and protection against environmental conditions and infection. However, animal cells do not have cell walls.</span>

Answer:
Option A
Explanation:
All four types of polysaccharides are homopolymers ie they are made up of repeating units of only one type of monomers.
Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.
In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.
The microorganisms found in soil are important because they affect the structure and fertility of soil. Certain bacteria responsible for nitrogen fixation converts nitrogen in the atmosphere, so that it can be used by plants. Because of microbes, nutrients and minerals are made available to plants. Soil with more diverse microbe will result in fewer plant diseases and better crop yield.
