what is life?

Post by Ambika79 » Tue Apr 19, 2005 3:13 pm

Hi, I'm new to this forum, but had an interesting thought this morning, and then happened to stumble upon this discussion while researching it. I'm not an expert on biology, but what I remember about how we define something as living, say a rock vs. a cat, included most of what's been said here, including the property of movement. Anyway, it occured to me that a living being encompasses all 3 stages of manner, i.e. solid, liquid and gas, in one complete being. I can't think of anything that has all 3 of these and that is not alive. Or vice versa. Can you :?:

We discussed it in the forum. there are some criteria to decide if something is living or not.

Well Abmbika u need to brush up your PHYSICS concepts as well !
I DO KNOW of such a substance(s) and is not ALIVE ...
At 'triple point' (a substance specific temperature) of a given substance, that particular substance exists in ALL THREE states of matter - solid, liquid and gas.

Howwwzzzzzaaaaaat :evil: !!!

biostudent84 wrote:Defining life:

Here is the current definition of life. In order for something to be called living, it must follow all of these:

1. all known living things are made up of cells.
2. the cell is structural & functional unit of all living things.
3. all cells come from pre-existing cells by division.
(Spontaneous Generation does not occur).
4. cells contains hereditary information which is passed from
cell to cell during cell division.
5. All cells are basically the same in chemical composition.
6. all energy flow (metabolism & biochemistry) of life occurs
within cells.

Disclaimer: This is not my own work...it is the work of the biological community. If you do not agree with it, go to the PhD's and all other scientists, don't bash me, :lol:


Isn't that the "cell theory" by definition?

Just trying to label it.

Yes, but with part 1, it doubles for a definition of life.

defining life is okay, but probably we were giving ranks to the degree of livingness And note non-living thing have 0 livingness while so there may be a gradual increase in livingness of things in thins world... :shock: , this was the attempt of inuyasha atleast. [and mine also. ] As definition of life has been given by scientists,
And Ambika79, :roll: if you analyse more eg.s then you u'll get why that can't be a definition.

biostudent and all who are reading or hav read this message... You r going into too much detail. There is no possible way to "define" life. life is a mysterious thing and it exists not to be defined. Life is not a technical thing it is simple and everthing that has life is individual. Some of u may not want to go into philosophy but it is the only way to come to and agreement. i do not wish to define life, only to give my opinion so, here it is. life is made up of many things and like all things in existance , it ends. Some people may say there is no real valuse in life, but what greater value is there than to have life? seriously, we wouldn't even be having this discussion if we didn't value or want to understand life, now would we. Oh and i may have contradicted myself several times in that discussion so it may e hard to look from my point of view.
