Cellular growth and development

Cellular growth and development refer to the processes by which cells increase in size, divide, and specialize to form different tissues and organs. Growth involves cells expanding and dividing through mitosis, while development includes cells acquiring specific functions and structures tailored to their roles. This process is regulated by genetic instructions and environmental signals, ensuring that organisms grow properly from a single fertilized egg into mature, functioning bodies. In essence, cellular growth and development are fundamental to the formation, maintenance, and repair of living organisms.
