From the previous  topic, we learned about test of significance, a procedure for comparing observed data with a claim or hypothesis or predicted data. This test of significant is used to test e claim about an unknown population and for testing the research hypothesis against the H0. Null …

The cell wall is structurally and chemically different from the protoplasm. The growth in thickness of walls is evident in both primary and secondary walls. The initiation of the cell wall and how it grows is being studied here. Origin of the Cell wall The wall formation is first evident …

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 …
