We say "unicellular organisms are said to be immortal” becausea)they ...
Unicellular organisms are said to be immortal because they continue to live as their daughter cells. This is explained below:
Reproduction in Unicellular Organisms:
Unicellular organisms are those that consist of only one cell, and they do not have any specialized tissues or organs. These organisms can reproduce asexually by a process called binary fission. In binary fission, the cell divides into two daughter cells that are genetically identical to the parent cell. Thus, the unicellular organism can reproduce throughout its lifetime by repeatedly undergoing binary fission.
Immortality in Unicellular Organisms:
When a unicellular organism undergoes binary fission, it produces two daughter cells that are identical to the parent cell. Each daughter cell can then undergo binary fission and produce two more identical daughter cells, and so on. This process can continue indefinitely, as long as the environmental conditions are favorable. Thus, the unicellular organism does not experience aging or death in the same way as multicellular organisms do.
Limitations of Immortality in Unicellular Organisms:
While unicellular organisms are said to be immortal, there are certain limitations to this. For example, the environment in which the organism lives can affect its lifespan. If the environment becomes unfavorable, the organism may not be able to survive and reproduce. Additionally, mutations can occur during the process of binary fission, leading to genetic variation and potentially harmful changes in the organism's traits.
Conclusion:
In conclusion, unicellular organisms are said to be immortal because they can continue to live as their daughter cells. This is made possible by their ability to reproduce asexually through binary fission. While there are limitations to this immortality, it is still an important characteristic of unicellular organisms that sets them apart from multicellular organisms.

We say "unicellular organisms are said to be immortal” becausea)they ...
The period from birth to the natural death of an organism is called its life span. Whatever is the life span, death is a must for every organism. No individual is immortal except some single-celled organisms such as Amoeba, bacteria, etc. They divide to form two offspring before becoming old by a process called binary fission. In this method, the daughter cells are simply the replica of their parent. So, logically when there's no difference between the parent and daughter cells, it can simply be put that what sort of Amoeba existing now is the exact same as the initial ancestor cell. Thus, there is no death for unicellular organisms that are reproduced by binary fission.
