Question
Explain arithmetic growth in plants.
✓
Answer
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. Mathematically, it is expressed as: $L_t=L_0+r t L_t=$ length at time ' $t$ ' $L_0=$ length at time 'zero' $r=$ growth rate/ elongation per unit time.
