Mark the correct statement/s about arithmetic growth.
Options
- AIn mitosis, only one daughter cell continues to divide while the other differentiates and matures.
- BL t = L 0 + rt
- CThe simplest expression of this growth is exemplified by a root elongating at a constant rate.
- DAll of the above
Correct answer
D. All of the above
Step-by-step solution
In arithmetic growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and matures. The simplest expression of arithmetic growth is exemplified by a root elongating at a constant rate. Look at Figure 15.5. On plotting the length of the organ against time, a linear curve is obtained. Mathematically, it is expressed as L t = L 0 + rt L t = length at time ‘t’ L 0 = length at time ‘zero’ r = growth rate / elongation per unit time.
