Plant Growth and Development

Growth is an irreversible quantitative change

Growth is an irreversible quantitative change in size. Development is the whole series of changes an organism passes through during its life cycle. De

Growth can be measured by increase

Growth can be measured by increase in length, diameter, volume, fresh weight, dry weight, area, or cell number. Common methods include direct measurem

Growth follows a sigmoid curve

Growth follows a sigmoid curve with three phases: initial lag phase, logarithmic or exponential phase, and stationary phase. Growth is slow at first,

The increased growth per unit time

The increased growth per unit time is growth rate. Arithmetic growth follows L_t = L_0 + rt. Geometric growth follows w_1 = w_0 e^(rt). Absolute Growt

Water

Water, oxygen, nutrients, temperature, light, soil conditions, pollutants, genetic factors, and hormones influence growth. Water supports cell enlarge
