(i) The growth of plants is due to the presence of meristem at certain locations in their body.
(ii) Growth wherein new cells are always being added to the plant body by the activity of the meristem is called the close form of growth.
(iii) In dicotyledonous plants and gymnosperms, the lateral meristems, vascular cambium and cork- cambium appear later in life. There are the meristems that causes increase in the girth of the organs in which they are active. This is known as secondary growth of plant.
(iv) Growth, at cellular level, is principally a consequence of increase in the amount of protoplasm.
(v) The period of growth is generally divided into 3 phases, namely, meristematic, elongation and maturation. The constantly dividing cells, both at the root apex and shoot apex, represent the elongation phase of growth.
(vi) Arithmetic growth is mathematically expressed as Lt = L0 + rt where 'r' is growth rate.
(vii) The exponential growth can be expressed as $W_{t}=W_0 e^{n}$ .
(viii) Measurement and comparison of total growth per unit time is called the relative growth rate.
(ix) Water provides the medium for enzymatic activities needed for growth.
(x) Cells derived from root apical and shoot-apical meristem and cambium differentiate and mature to perform specific functions. This act leading to maturation is termed as dedifferentiation.
(xi) During differentiation, cells undergo few to major structural changes both in their cell walls and protoplasm.
