Major themes of Biologyh

Major themes that unify biology include structure and functioning of cells which are basic building blocks of all organisms, inheritance of biological information in the form of DNA, unity and diversity of life through evolution, and flow of matter and energy through cycles of life.

It is interesting to understand the hierarchical organization of structures extending from molecules to bio-sphere and how incremental changes add to the changes in properties.

It is amazing to know that just 4 elements constitute 96% of living matter with water as solvent of life. In fact, the above are just a tip of the iceberg. Inside the web pages you will find a whole host of topics ranging from plant form and function to animal form and function, from human physiology to health, from evolutionary biology to ecology, and from biochemistry to molecular genetics. The concepts and principles are well laid with practical examples and visualized with clear graphics for your clarity.
