Organisms grow because they constantly undergo cell division. In order for cell division to take place, organisms need a constant supply of nutrients and oxygen. In addition, they rely on signaling processes to ensure the cells divide correctly.Continue Reading
Cell division is a process that takes place constantly. This occurs under mitosis, which involves a diploid cell dividing to produce two more daughter diploid cells. During this process, genetic information is copied via the chromosomes, resulting in a cell that fulfills the same function. For example, when someone's bones are growing, the cells divide to develop the bone structure. Mitosis applies to the cells of the body, or somatic cells, whereas meiosis is used during the growth of reproductive cells.
Cell division is a mediated process. When there is a need for cells to divide, they communicate with each other using cyclin signals, which are special proteins. In addition to telling cells when to divide, they tell them to stop. To achieve this process, cells need nourishment in the form of oxygen, glucose and other nutrients. With these nutrients, they move through the ATP cycle, which also helps them carry out their functions. For example, when someone is working out and they injure a muscle, they need the ATP cycle for muscle contraction and to promote muscle repair.Learn more about Biology
