“The animate existence or period of animate existence of an individual.”
If you want to get scientific then life must have an RNA structure, and that RNA structure must be producing and synthesizing protein (to my understanding). Life is classified into three Domains: Archaea, Bacteria, and Eukarya.
There is one thing that the three domains have in common though, and that is they have an RNA structure. They are classified into different domains because their structures differ. RNA structures share one thing in common though: ribosomes. Ribosomes produce proteins. But the difference between a “dead being” and a “living being” is whether or not the ribosomes is actually producing and synthesizing protein.
I presume the proteins are Adenine, Guanine, Thymine, and Cytosine, which cause DNA to synthesize (to my understanding). So without these proteins there wouldn’t be DNA and then ribosomes wouldn’t exist and obviously there would be no such thing as an RNA structure, causing no life form. And for a life form to actually live, ribosomes must produce proteins in order for DNA to synthesize.
DNA retains cellular function data, causing the ribosomes to continue producing proteins which causes the DNA function to continue retaining the data. Basically, DNA and ribosomes and so forth act as a clock to my understanding. It might be even more complicated than but I guess that’s the basic small grasp of biology.
But obviously small beings (like bacteria) with just a few cells and larger beings (like humans) with millions of cells, the determination of whether or not a being is alive is drastically different.
Just because one cell on a human body is dead does not necessarily mean that person is dead but if all our cells were dead then we surely are dead as a door nail. Ribosomes in cells are basically what our brains are to us humans. But another observation is that just because our brain is dead does not necessarily mean that all of our cells are immediately dead. Nonetheless, because of our brain being dead, all of our cells will die and decay, producing no new cells.
Our many brain cells function together like one big ribosome, producing what our bodies need in order to work like a clock, which is why if our brain dies, our body dies with it. The question I guess remains, why does our brain still function if one brain cell dies or a quite large chunk of our brains are taken out? Since cells regenerate when they die, just because one cell is dead doesn’t necessarily mean the whole brain will die, therefore you die.
Well, if the part of your brain that makes some bodily functions work, then that part will no longer function. With today’s technologies, someone may to live through artificial means such as medication or modern gadgets. But without the means of this support, that part of the body’s cells will eventually die off, causing further repercussions like a domino effect all because apart of the brain for that body function ceases to exist. Or sometimes part of the brain that is damaged (all the brain cells in that area are dead) or is taken out does not actually mean a body function is affected so that person may continue to live, however, some part of them (like speech or eyesight) may no longer function but those features are not needed to live.
Brains also have proteins, and I am not a brain expert, but I guess brains could potentially produce proteins which produces in turn produces the matter inside your brain, which continues to produce proteins kind of like Ribosomes and the DNA clockwork I described earlier. I’m not sure if that’s true or not and I am making a baseless assumption but that’s how I think that of it and will describe it here.
In conclusion, the brains in beings with complex structures are what ribosomes are to simple-celled structures.
Now what about plants? They have no brain and are also complex structured beings. Well, same concept with the brain except with part of the cell that takes in sugar, I think called Mitochondria.
Without sugar plants wouldn’t be able to function in their complex state. So, they wouldn’t exist without the ability to take in sugar. Since plants are complex structures like humans they can live if they are missing a few cells or some portions cut off to an extent.
I haven’t took a biology course in… 6-7 years and that was only a High School class but I also only learned about the cellular structure two times before then. So I could be wrong about the job of the Mitochondria but I think I am not wrong.
Again due to the complex structure of a plant the Mitochondria being in the structure, all other functions are caused by a clockwork rotation between sugar from the sun and water and the Mitochondria. When the clock stops the life form is no longer living.
So, ya this is the basics of a life form and what determines whether or not it is alive.

I don’t study biology or medical applications but I do talk about the things I do know, I think I know, and my overall idea of life form concepts. So, if I said something that perhaps is inaccurate let me know and I will try to rework this post out.
