If a single cell dies in a multi-cellular organism, what happens to the organism

Answers

This process is normal in all multicellular organisms, if one cell dies because it is old, another one is born to replace it.

Explanation:

This process is called cell death and is the cycle of life throughout the earth a very clear example is human hair, daily hair falls out but at the same time you grow again, the problem would be when cell death began very fast and not replaced by new cells accordingly we would have diseases such as necrosis

Generally speaking, it would not affect the organism. For humans, we regularly replace our cells in our body, so even when our cells die, we are fine.
