In order to replace the cells that are dieing
cell division is how organisms grow.
Ribosomes are needed to produce protein in cells.
No to cannot live without cell division because our cells need to divide to make us grow. Also we need cell division to survive because our cells only live for a limited amount of time, so if our cells don't divide then the cells will just die and we won't survive.
Cells need to divide to grow, repair damaged tissues, and replace old or dying cells. Cell division allows for the distribution of genetic material to new cells, ensuring the continuity of life. Without cell division, multicellular organisms would not be able to develop, maintain, or regenerate their tissues and organs.
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
T plasma cells, if your at A level or anything lower, you don't need to write anymore than that. T plasma cells are formed through clonal selection.
Because body cells need to make genetically identical daughter cells and sex cells need to make genetically unique cells with half the genetic material of the parent cell.

Adding more cells
No, all cells do not divide at the same rate in mitosis. The rate of cell division can vary depending on the type of cell, its stage in the cell cycle, and external factors such as growth factors or signals from neighboring cells. Some cells may divide rapidly, while others may divide more slowly or even be in a resting state.
Cells need to produce new cells in order to grow, repair damaged tissues, and replace old or dying cells. This process, known as cell division, is essential for the maintenance and regeneration of tissues and organs in multicellular organisms.
The usual somatic gene complement number = 2N. Upon genomic replication the gene complement number is 4N. Somatic Cell division 'reduces' the number 'back to' 2N. Gametic Cells, egg and sperm, need to "divide again" in meiosis to further reduce the gene complement number down to the required 1N [again, for gametic cells only].
