A layer of structural materials composed of polysaccharides, glycoproteins, and phenolic compounds found external to protoplasm is called the cell wall. Certainly, it defines the shape and size of the cell. In this paragraph, the structure and composition of cell walls will be discussed explicitly. Gross Structure of Cell Wall The …

In the experiment, we measure the two continuous characters which are associated with each other. For example, the height of the plant and the temperature of the atmosphere. Accordingly, to understand the relationship between two such variables, we need to know how they are related and how the relationship can …
