Here's why:
* Development is a broader term than just growth. It includes not only increases in size (growth) but also changes in structure, function, and complexity.
* This can include things like:
* Cellular differentiation: Cells specializing into different types with unique functions.
* Morphogenesis: The development of the organism's shape and form.
* Maturation: The process of reaching full functional capacity.
* Aging: The gradual decline in function over time.
Therefore, development encompasses the entire life cycle of an organism, from fertilization to death, encompassing all the changes that occur along the way.
