DNA damage is defined as an alternative to DNA structures that can cause cellular injury and reduces the organisms efficiency or reproductive fitness. DNA damage may occur by free radical, physical agents like UV rays, X rays and chemical agents like aflatoxine, alkylating agents, hydraxines. Further, DNA damage is intertwined …

Air Plants: Plants That Grow without Soil
When you hear the name of the word ‘plant’, first the thought will come to your mind that plants grow in the ground and can’t develop, reproduce and even survive without the existence of soil. The soil provides all the elements for its survival. But have we ever heard that …

It’s always helpful and extra-beneficial to check the background or history before learning a new subject matter. Why? Because this enrich us with some fundamental concepts behind the topic and enable us to understand how versatile ideas bloom and differentiate to shape a new body of knowledge. Isn’t that interesting!!! …

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 …
Read More »Cell wall: Structure and Composition
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 …
