tissues and fibres.
Phase of maturation- the enlarged cells develops into special or particular type of

Growth Rate- increase in growth per unit time is called growth rate. Growth rate may
be arithmetic or geometrical.

arithmetic progression- 2,4,6,8 ……. It is found in root and shoot elongation.
L = L + rt

t
Length after time = length at beginning + growth rate x time.
