Primarygun Posted September 29, 2004 Share Posted September 29, 2004 How do scientists classify the structures of a cell into living and non-living? Cell wall is non-living, while chloroplast is living. Does the word "living" implies "life" or carbon structure? Link to comment Share on other sites More sharing options...
Edisonian Posted September 29, 2004 Share Posted September 29, 2004 I think living cells collect or expend energy. Is this right? Link to comment Share on other sites More sharing options...

[/quote'] It might have something to do with the fact that chloroplast ( and mitochondria) have their own separate DNA. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/Endosymbiosis.html Not sure though...

LucidDreamer Posted September 30, 2004 Share Posted September 30, 2004 I believe that a cell is the smallest single unit of life. I don't think they break it down any further. I don't think that a chloroplast or a mitochondria are considered to be alive. They are organelles that use to be single celled organisms themselves before they were incorporated into the eukaryotic cell. Now that they are part of the Eukaryotic cell they are not considered to be alive themselves. Its the whole cell that is considered living. At least that's how I learned it.

You forget viruses... a hell of a lot smaller than cells. Link to comment Share on other sites More sharing options...
LucidDreamer Posted October 1, 2004 Share Posted October 1, 2004 I think the majority of scientists don't consider viruses to be alive. Link to comment Share on other sites More sharing options...
