What is growth? How will you measure the rate of growth?
Growth is defined as a permanent or irreversible increase in dry weight, size, mass or volume of a cell, organ or organism. Generally growth is accompanied by metabolic processes (both anabolic and catabolic). At the cellular level, growth is due to increase in amount of protoplasm. However, it is difficult to measure increase in protoplasm. Increase in protoplasm leads to increase in cell, cell number and cell size. This fact is used in calculating growth which, therefore, is a quantitive or measurable phenomenon. The parameters used for measuring growth increase in fresh weight, dry weight, length, area, volume and cell number.
