I"ve always wondered why cells have actually only one nucleus, as having actually multiple would certainly seemingly prevent mutation. Are there examples of organisms through multiple nucleuses? If not, is tbelow a reason?

Are tbelow examples of cells with more than one nucleus?

Yes, they are referred to as Multinucleate cells. There are two kinds of multinucleated cells

SyncytiaCoenocytes

I highly recommend having actually a look at this answer for the interpretations.

You are watching: Why do some cells have more than one nucleus

Examples of Syncytia include

OsteoclastsSkeletal muscle fibers (many thanks
GerardoFurtado; view photo below)Blastoderms at an early stage in the advance of a fruit fly

Are there examples of organisms through multiple nucleuses?

Side note: The plural of nucleus is nuclei

In many type of fungi, throughout sex-related reproduction, a fusion of cytoplasm take place beforehand in the mycelium however a fusion of the nucleus happens only exceptionally late (simply prior to sporulation). This is a type of Coenocytic mycelium. In these species, non-negligible fractions of their cells are multinucleated.

Tright here are endosymbiotic and endoparasitic eukaryotes in various other eukaryotes that would certainly lead to a cell containing a number of nuclei yet that would certainly not count I would guess as the nuclei belengthy to various species.

Picture of Codium. The whole algea is a single multinucleated cell.

$egingroup$ "I doubt there are species where all cells are constantly multinucleated".. except for the gamete phase, that's specifically the case for numerous species of algae and protozoa, in which all cells are always multinucleated (+1 though). $endgroup$

There is a branch of life dubbed the Diplomonads, most of which have two nuclei. They are single cell organisms and an early offshoot of the eukaryotic linage. A excellent instance is Giardia lamblia.https://en.wikipedia.org/wiki/DiplomonadGiardia lamblia

According to this post The hairy beast via seven fuzzy sexes

Tetrahymena thermophila has two: a large macronucleus and a small micronucleus. The macronucleus controls the daily functions of the cell, while the micronucleus deals with its complex sex life. In reality this is true for all ciliates.

When a "slime mold" enters the "plasmodium" phase n cells merge together to develop one cell via n nuclei. This suggests plasmodiums deserve to have thousands or tens of hundreds of nuclei...

Skeletal muscles (striated) are multi-nucleated-have actually more than one nucleus per cell as they are formed as an outcome of the fusion of myoblasts.
