Growth is the biological process involving an irreversible increase in size and mass of an organism over time, typically through cell division and enlargement. It includes both visible physical changes, such as getting taller or gaining weight, and internal developments like the growth of organs and tissues. Growth is regulated by genetic factors and influenced by environmental conditions such as temperature and light. In multicellular organisms, growth occurs as cells divide (mitosis) and then expand, contributing to the overall increase in body size and complexity. Growth usually follows a predetermined pattern that shapes the organism's final size and form. It is a fundamental characteristic of living things and can continue throughout life, although the rate typically slows down after maturity. Additionally, growth can also refer to repair processes, such as regeneration of tissues after injury
. In summary, growth is:
- A biological unfolding of events where an organism becomes larger or more complex.
- Driven by cell multiplication and expansion.
- Influenced by genetics and environment.
- A process that can involve both development and maturation.
- Sometimes associated with pathological growth, such as tumors, when abnormal
