Growth is the increase in size of an organism or one of its parts. Development is the process of growth and change that happens during the life of an organism.
Both growth and development are essential for the survival of any species. All organisms must grow in order to survive and reproduce. They must also develop so that they can adapt to their changing environment.
Organisms grow by increasing the number of cells they have. They develop by becoming more complex, improving their ability to function properly, and adapting to their environment.
One example of growth is when a human embryo grows from a single cell into a baby with billions of cells. This happens because the cells divide and multiply very quickly at first, then slow down as the baby becomes larger.
One example of development is when a human child grows up and learns new skills such as walking, talking, and reading. The child’s brain develops so that it can control these new skills. The child also develops physically, growing taller and gaining more muscle mass.
