Cell division is essential for growth and repair from "summary" of NCERT Solutions - Biology for Class 12th by Dr. Madhurbhashini,Sargam Hans,Shanya Hans
Cell division plays a crucial role in the growth and repair of living organisms. It is a fundamental process that allows organisms to increase in size and replace damaged or worn-out cells. Without cell division, growth and repair would not be possible, leading to stunted development and impaired ability to heal from injuries. During growth, cell division allows multicellular organisms to increase in size by producing more cells. This process is essential for the development of tissues, organs, and ultimately the entire organism. Without cell division, organisms would not be able to grow beyond a certain point, limiting their potential for survival and reproduction. In addition to growth, cell division is also essential for the repair of damaged tissues. When cells are injured or die, they need to be replaced to maintain the structural integrity and function of the organism. Cell division allows for the rapid production of new cells to replace the ones that have been lost, ensuring that the organism can recover from injuries and continue to function properly. Furthermore, cell division is necessary for the regeneration of tissues in response to injury. In some cases, such as in the liver or skin, cells have the ability to divide and proliferate in order to repair damaged tissues. This process is crucial for the healing of wounds and the restoration of normal function in the affected area.- Cell division is a fundamental process that is essential for the growth and repair of living organisms. Without this process, organisms would not be able to increase in size, replace damaged cells, or regenerate tissues in response to injury. By allowing for the production of new cells, cell division ensures the proper development and function of multicellular organisms.
