Growth is the process of increasing in physical size. In living organisms, growth involves an increase in the number of cells and the size of these cells. It is a fundamental characteristic of all living things and is essential for their survival and development.
Several factors influence the growth of living organisms including:
Plants exhibit growth through the process of cell division and elongation. The growth of plants is influenced by factors such as sunlight, water, soil nutrients, and hormones such as auxins and gibberellins.
Animals grow through a combination of cell division and hypertrophic growth. Growth in animals is also influenced by genetic factors, nutrition, and hormonal regulation. Growth rates vary among different species of animals.
