Unicellular organisms that reproduce by mitosis are considered immortal because they can continuously replicate their genetic material without aging or experiencing cell death. This allows them to potentially live indefinitely as long as they have the necessary resources for growth and reproduction.
Unicellular organisms are often referred to as immortal because they can replicate indefinitely through a process called binary fission, where they divide into two identical daughter cells. Additionally, some unicellular organisms, like certain strains of bacteria, have the ability to form dormant structures called endospores, allowing them to survive harsh conditions for extended periods of time.
Plants are not immortal and eventually succumb to the passage of time like all living organisms.
An immortal cell line is a population of cells that are able to constantly replicate indefinitely or have a very high replicative capacity due to mutations that prevent normal cellular aging processes. These cell lines are commonly used in research and biotechnology for their ability to grow continuously in culture. Examples include HeLa cells and HEK 293 cells.
This is a very simple answer: If it's alive, it reproduces. There is no such thing as an immortal organism. They all die, and to continue the survival of the species they must all reproduce before they die. To keep the species stable, complex animals that reproduce by sexual reproduction and are either male or female must replace themselves - two offspring per female in her lifetime. There must also be enough extra young to cope with those that die before reproducing.
Yes, ever since ancient times it has been known that a male vampire can impregnate a human woman. The child is known as a Dhampir. These children have all the powers of a vampire (in ancient times that meant only the power to steal life-force, all this super-power nonsense is late 19th century and Hollywood conceived) but as they are already alive, they have no need to steal life-force. This power lies dormant until they themselves die, or are near death, and they have cause to employ it. I know of non instance where a female vampire has given birth.

In most stories, immortal beings cannot reproduce. Reproduction is only necessary to maintain a species' existence. Since immortal beings will always exist, there is no need for them to reproduce.
yes they are considered immortal they are dead
Plants are not immortal and eventually succumb to the passage of time like all living organisms.
In many mythologies, gods are considered immortal beings who do not die.
This varies enormously from species to species. Most single cell organisms can even be considered immortal. they just divide in two with neither cell being identifiable as being the "new" cell.
Jackie has had two film where he could be considered immortal. The 'best' one is probably 'The Medallion' with Lee Evans, but he could also be considered immortal in 'The Myth' depending on how you interpret the film.
Apollo was considered to be immortal in Greek mythology as he was a god, specifically the god of music, prophecy, and healing.
Ares is considered an immortal in Greek mythology. He is the god of war and a son of Zeus and Hera.
In Greek myth, yes.
Cells exhibit an effect known as the Hayflick limit, which states that all cells can divide and reproduce only a limited amount of times. There are a few exceptions to that rule, as some cells known as immortal cells display no signs of aging and can be terminated only by outside factors, such as starvation or if their host dies. Human germ cells (ovum and sperm) have no Hayflick limit. Many species of bacteria are considered immortal as they continue dividing until an outside force terminates them. Similarly, diseases of the cell cycle (such as cancer) are able to produce immortal cells as they grow and reproduce without limitations.
Greek gods are considered immortal beings in Greek mythology and cannot be killed in the traditional sense.
