Question
Describe briefly:
Arithmetic growth.
Solution
If the length of a plant organ is plotted against time and shows a linear curve, the growth is called arithmetic growth. In this growth, the rate of growth is constant and increase in growth occurs in arithmetic progression.
For example, the length of a plant is measured as 2, 4, 6, 8, 10, or 12 cm at a definite interval of 24 hours. It is found in root or shoots, elongating at constant rate. Arithmetic growth is expressed as Lt = L0 + rt.
Here, Lt = length after time t. L0 = length at the beginning; r = growth rate
