PLant Growth

Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth, and is the result of cell division in the shoot apical meristem.Growth refers to the increase in mass and size of a body or organs. It typically occurs through the multiplication of cells and an increase in intracellular substance. Development refers to the physiological and functional maturation of the organism.
