What is the formula for arithmetic growth given in the text?

Options

  1. ALt = L0 + rt
  2. BLt = L0 * rt
  3. CLt = L0 / rt
  4. DLt = L0 - rt

Correct answer

A. Lt = L0 + rt

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. On plotting the length of the organ against time, a linear curve is obtained. Mathematically, it is expressed as Lt = L0 + rt
