5.Purpose of Cell Division- state the 3 functions

Cell division serves three critical functions in living organisms. Firstly, it enables growth by increasing the number of cells, allowing organisms to develop from a single fertilized egg into complex beings. Secondly, it facilitates repair and regeneration, replacing damaged or dead cells to maintain healthy tissues. Lastly, it plays a vital role in reproduction; in single-celled organisms, it allows for asexual reproduction, while in multicellular organisms, it contributes to the formation of gametes, ensuring genetic diversity in offspring. An interesting fact about cell division is that the process doesn’t just happen randomly! In multicellular organisms, controlled and precise division is key. The body employs a variety of cell signaling pathways to ensure that cells only divide when necessary. This regulation helps prevent diseases like cancer, where unregulated cell division can lead to tumor formation. So, each time your cells divide, there's a meticulous plan behind it!
