Do unicellular organisms live longer than multicellular orgnisms?

Unicellular organisms often have shorter lifespans compared to many multicellular organisms. For example, bacteria can reproduce rapidly, leading to brief individual lifespans of hours to days. In contrast, many multicellular organisms, such as trees or certain mammals, can live for decades or even centuries. Therefore, while some unicellular organisms may have quick generational turnover, multicellular organisms generally have longer lifespans.
