● `color{Brown}"Growth"`, at a `color{violet}"cellular level,"` is principally a consequence of `color{violet}"increase"` in the `color{violet}"amount of protoplasm"`.
● Since `color{violet}"increase in protoplasm"` is difficult to measure directly, one generally `color{violet}"measures some quantity"` which is more or less `color{violet}"proportional to it"`.
● `color{violet}"Growth"` is, therefore, measured by a `color{violet}"variety of parameters"` some of which are:
`star` Increase in `color{violet}"fresh weight"`, `color{violet}"dry weight"`, `color{violet}"length, area, volume"` and `color{violet}"cell number"`.
● It is amazing to know that `color{violet}"one single maize"` `color{violet}"root apical mersitem"` can give rise to more than `color{violet}"17,500 new cells"` per hour, whereas cells in a watermelon may increase in size by upto `color{violet}"3,50,000 times"`.
● In the former, `color{violet}"growth"` is expressed as `color{Brown}"increase in cell number"`; the `color{violet}"latter expresses"` growth as `color{Brown}"increase in size"` of the cell.
