Growth refers to dimensional augmentation, cellular multiplication, or quantitative changes in size, weight, and number. Development involves a progressive, orderly series of changes leading to maturity. The key differences between growth and development are: (1) Growth refers to changes in quantitative aspects like size, while development refers to qualitative changes resulting in improved functioning. (2) Growth stops at maturity but development is continuous throughout life. (3) Development is a broader term that can include growth as one aspect, but also includes physical, social, emotional, and intellectual changes.
