Growth in unicellularorganisms occur by growth of their cell. ... For many tissues in a growing individual, yes, there is a big increase in cell number(eg, bone growth). Other tissues, like the heart, reach the adult number of cells early and increase in cell size as the individual grows or it responds to work.

cell division. Each cell give rise 2 new daughter cells (in mitosis) and 4 new daughter cells (in meiosis).
In plants the cell division occurs through out there lifespan.
BUT
In animals the cell division occurs only up to a certain period of time and after that there stop diving. One such Example is the cells of our eyes ( the eye cells don't divide throughout our lifespan there stop dividing at certain age)
