Solution
The correct option is C Grand period of growth The growth of plant organ or a whole plant characteristically passes through different phases. Usually, under suitable conditions, there is an increase in the plant growth. Growth is slow at first (lag phase) then gains speed (log phase) and eventually slows down (decreasing the growth rate) to come to a halt (steady state). The total time during which this course of growth takes place is called as a grand period of growth.
