During mitotic cell division in lobsters, as well as in other organisms, the primary purpose is the growth and replacement of cells. This process is crucial for the organism's overall development and maintenance of its tissues. Mitosis allows for the production of new cells that are genetically identical to the original cell. This is essential for tissue repair and growth, particularly in lobsters, which undergo molting to grow, necessitating the generation of new cells to replace those that are shed.

Lobsters, like many multicellular organisms, utilize mitosis for the expansion of tissues, enabling them to grow larger as they age. This cellular proliferation is fundamental to maintaining the organism's structure and responding to environmental demands or physical injuries. Other processes, such as repair of broken tissues or energy production, while vital for an organism's survival, are not the direct outcomes of mitosis itself. Additionally, the formation of gametes involves meiosis, a different type of cell division responsible for creating reproductive cells, rather than mitosis.
