Why exactly might mitosis be though of as cellular immortality?

I know this is true for sure because I heard my teacher say so; however, I forgot hearing her saying why and how...
So If someone may please explain, I'd really appreciate it :D
Mitosis is the process by which a single cell divides into two identical daughter cells. It is a crucial part of the cell cycle and allows for growth and repair in multicellular organisms.
Mitosis is a continuous process that allows cells to divide and replicate indefinitely. This means that a single cell can theoretically produce endless generations of identical daughter cells, leading to cellular immortality.
No, there are other factors that contribute to cellular immortality such as telomere maintenance, DNA repair mechanisms, and cell signaling pathways. However, mitosis is a crucial component as it allows for the continuous division and replication of cells.
Not all cells are immortal through mitosis. For example, nerve and muscle cells in humans do not undergo mitosis and have limited lifespans. However, some cells such as stem cells and cancer cells have the ability to continuously divide through mitosis, leading to cellular immortality.
Yes, mitosis can go wrong and lead to cellular mortality. Errors in the mitotic process, such as chromosome missegregation or abnormal cell division, can result in cell death or mutations that can lead to diseases such as cancer.
