Organism A was found in the deepest layer, organism B in the layer on top of that, and organism C in the top layer. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. To achieve the outcome of identical daughter cells some steps are essential. In multicellular organisms, individual groups of cells have become specialized to perform particular . Advantages of Multicellular Organisms. The 3 main reasons that cells divide are: - To help multicellular organisms grow and develop - To help multicellular organisms heal - To help unicellular organisms reproduce. 3 reproduction.

Survival of the eukaryotes depends upon interactions between many cell types and it is essential that a balanced distribution of types be maintained. Why Do Cells DIvide? Before a cell can divide . Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences. Usually when a stem cell divides into two one daughter cell goes on to make a more specialized type of cell or even gives rise to several different cell types. Cells must divide when they reach a certain size because their ability to transport necessary substances to all parts of the cell and remove wastes from all parts of the cell decreases as the cell grows larger and its surface area to volume ratio increases. It is important because we need cells to be able to repair or bodys and reproduce destroyed cells. Organisms can repair some of their tissues, using mitosis to regenerate new cells.
