Importance of growth and development in living organisms

In multicellular organisms, the newly formed individuals have certain structures that are not well developed. Growth and development enable the differentiation of cells in an organism, resulting in the specialisation of cells for different function. the specialisation of cells during growth enables an organism to adapt to its environment. An example of specialised cells is guard cell in the plant leaves which control the opening and closing of stomata and blood cells used to transport different materials in various parts of the animal body.
