Biological growth refers to the process by which living organisms increase in size and mass over time. This growth occurs through cell division and the accumulation of new cells, which can happen in various ways depending on the organism. For example, plants grow by adding new cells at their tips, while animals grow by increasing the number of cells throughout their bodies. Factors influencing biological growth include genetics, nutrition, and environmental conditions. Genetics determines the potential size and growth rate of an organism, while nutrition provides the necessary energy and materials for growth. Additionally, environmental conditions such as temperature and availability of resources can significantly impact growth rates.
