Is There A Living Thing With NO CELLS?

I would be more than happy to call a circulating RBC 'a dying cell on its last breath lasting 120 days'.

[MrMistery]

well that's kinda what I was saying...

[hanhan2008]

Virus IS a good answer. Maybe prion is another answer.

[MrMistery]

sorry, neither of them is alive. See your introductory biology book if you don't believe me

I ran this question by my Bio instructor. He kinda agreed with your definition, but he sorta waivered on it. I could tell the question made him go Hmm.

The problem with Biology is that there isn't an adequate definition of "Life".
There are always exceptions to be found.

A definition of life for me would simply state the ability of a collection of molecules to replicate and to act as a catalyst. Ie RNA alone would qualify as life. So in my definition
viruses would also have to be included just as any other 'parasite' which we see currently see as being alive, but which cannot survive without a host .

Yeah, I guess there will always be a difference of opinion. People arre always telling me to get a life. I guess synthesis of protein is not good enough for them

Hahaha classic biology teacher method. My grade 12 bio teacher did a similar thing, he said anyone to make a lazer beam that can burn a piece of paper out of a lazer pointer would get an A. He is clearly proving a point, he is saying that, because living things without cells does not exist.

Sorry budday.

[sonawanes61]

are yaar life originated frm cell so how can their be organism alive without cell

[genovese]

Which came first, the cell wall or the molecules which provide the chemistry for life?
The chicken or the egg?
