A primary root grows from 5 cm to 19 cm in one week. Calculate the Absolute Growth Rate (AGR) and Relative Growth Rate (RGR) over this period:

(A)AGR = 14 cm, RGR = 2.8Correct
(B)AGR = 2.8 cm, RGR = 14
(C)AGR = 19 cm, RGR = 3.8
(D)AGR = 14 cm, RGR = 0.73

Answer: (A)

Solution

**Absolute Growth Rate (AGR)** = L1 - L0 = 19 cm - 5 cm = **14 cm** per week. **Relative
