Ecological Pyramid: Types and Significance

G. Evylen Hutchinson and Raymond Lindeman first discovered the ecological pyramid. They graphically presented the definite relationship between the various forms of organisms such as producers and consumers at different trophic levels and made the graphical presentation which looks like a pyramid. In this case, the producers make up the base and the successive level … Read more

Glycolysis: Features, Steps and Significance

Glycolysis is the metabolic pathway where one molecule of glucose (C6H12O6) converts into pyruvic acid with the help of enzyme. Glycolysis occurs in the cytoplasm of the cell during both anaerobic and aerobic respiration. It is also known as EMP pathway i.e., Embden-Meyerhof-Parnas pathway named after German Biochemists Gustav Embden, Otto Meyerhof, and Jakub Karol … Read more

Respiration: Types and Significance

Respiration is basically an energy releasing and supplying process. It held in each cell of the plant. Its primary stages take place in the cytoplasm and secondary stages in mitochondria. Actually respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert kinetic energy from nutrients … Read more

Hormone, Definitions, Properties and Chemical Natures

Image of Hormone

The word ‘Hormone’ is derived from Greek word ‘hormao’ which means “I impel” or “I arouse to activity”. William M. Bayliss and Ernest H. Starling (1904) termed that important chemical substance as hormone though it was first proposed by W. B. Hardy.  In animal physiology, it denotes a specific substance which is effective in a … Read more

Difference Between Plant Mitosis and Animal Mitosis

The cell division is the process by which organisms generate new cells. By this process, a single parent cell divides and creates identical daughter cells. During cell division, the parent cell duplicates its genetic material (DNA) and transmits to the daughter cells.  There are three types of cell division such as amitosis, mitosis and meiosis. … Read more
