growing

Growing is the process of increasing in size, number, or complexity over time. It occurs in living organisms as well as in social, economic, and environmental systems, and can refer to physical expansion, development, or maturation.

In biology, growth commonly means an increase in size and mass due to cell division and expansion. In animals and humans, growth involves cell proliferation and differentiation, regulated by hormones and genes. In plants, growth is driven by meristems at root and shoot tips, enabling directional growth influenced by hormones such as auxins, cytokinins, and gibberellins, and by environmental cues like light and gravity. Growth is often studied through measures such as body size, weight, organ size, or biomass.

Population growth describes how the number of individuals in a population changes over time. In the absence of limits, populations may grow exponentially, but real systems show density-dependent factors that slow growth as resources become scarce, leading to logistic growth with a carrying capacity.

Economic and social contexts use growth to describe increases in output, income, or development. Economic growth is usually quantified by increases in real gross domestic product (GDP) per capita and is influenced by investment, technology, and institutions. Personal growth refers to skill development, education, and changes in abilities and well-being.

Understanding growing requires specifying the context, since mechanisms, measurements, and implications differ across biological, ecological, and human systems. Growth processes are often studied to predict trends, optimize conditions, and assess health and development.
