24. Growth is one of the characteristic of all living organism? Do unicellular organism also grow? If so, what are the parameters?
Growth is the main character which distinguish living organisms from non-living. All living organism grow in number and then accumulate biomass and growin size as well.
The growth is exhibited by all living organismsin terms of increase in number of cells as well as increase in size and length of each cell.
In unicelluar organism, show growth and the growth is synchronous with reproduction. Unicellular organism when divide they produce offsprings (reproduction) i.e., each cell accumulate (synthesise) protoplasm and increasein size but up to a limit and divide to from two cells.
