Growth is the process of increasing in size and weight, which is irreversible. It can be measured and stated in number.
Development is the process of altering in shape (morphogenesis). It cannot be stated in number'
Growth and development experience several phases, i.e cell division phase, cell elongation phase, and cell differentiation phase.
Plant growth occurs because of the activity of meristematic cells
Meristematic cell activities inducing plant elongation is called primary growth. The activity of meristematic cells which causes increasing diameter in stem and root is called secondary growth.
Factors influencing growth consist of external and internal factors. The external factor are water, oxygen, carbon dioxide, temperature, light, nutrient in soil, and pollutant The internal factors are gene and grow the hormone.
