Introduction :-
Growth is one of the characteristic features of living organisms. Growth as a phenomenon has two aspects viz. quantitative and qualitative.
Quantitative aspect :- It is about the increase in the length, breadth, size, volume, body mass or dry weight and number of cells. Growth as a quantitative change is a final end product of successive metabolism.
Qualitative aspect :- It is about the change in the nature of growth where development is an ordered change or progress while differentiation leads to higher and more complex state.
Growth thus can be defined as permanent, irreversible increase in the bulk / mass of an or-ganism, along with the change of form.
In multicellular (vascular) plants, growth is indeterminate and occurs throughout the life indefinitely.

Root and stem show indefinite or indeterminate growth.
While, in organs like leaves, flowers and fruits, growth is determinate. i.e. they grow up to certain genetically destined size.
In unicellular plants, growth is uniform and determinate.

In unicellular plants, growth is uniform and determinate.
Growth is restricted to some specific region called meristems. Meristems are of three types based on location viz. Apical, Intercalary and Lateral.
