It occurs in several stages: prophase, metaphase, anaphase, and telophase, ensuring that each new cell receives an exact copy of the organism&#8217;s DNA. As a fertilized egg undergoes mitosis, it increases in cell number, leading to the development of a multicellular organism. This process is crucial for embryonic development, tissue repair, and even replacing old or damaged cells in adulthood.<\/p>\n\n\n\n<p>However, growth is not solely dependent on mitosis. Cell enlargement also contributes to growth, as some cells increase in size rather than simply dividing. Additionally, apoptosis (programmed cell death) helps shape developing tissues and organs by removing unnecessary cells, demonstrating that growth is a balance of cell division, differentiation, and controlled cell death.<\/p>\n\n\n\n<p>Despite all cells originating from a single fertilized egg and having the same DNA, they do not all function the same way. This is due to <strong>cell differentiation<\/strong>, where certain genes are turned on or off in different cells, leading to specialization. Differentiation occurs in response to signals from the organism\u2019s environment and other cells, allowing cells to develop unique structures and functions. For example, muscle cells have more mitochondria for energy production, while nerve cells develop long axons to transmit signals. Other specialized cells include red blood cells (which transport oxygen), white blood cells (which fight infections), and epithelial cells (which form protective barriers).<\/p>\n\n\n\n<p>Without differentiation, complex organisms could not function efficiently.
