Specimens from my home
 
 

 Fungi

The next two specimens are a pair of mushrooms, members of the fungus kingdom.  The one on the left was just picked from where it was grew up in my front yard after a rain.  The second is a dried mushroom from my pantry.
 
 

Plants

The last two specimens are members of the plant kingdom.  The first is dried leaves of the oregano plant.  Leaves of a plant cut off from the plant are dead.  The kidney bean, however, may or may not be alive.  The only way to be sure is to put it in contact with water and see whether it grows.  The ability to to produce seeds that can remain dormant for long periods of time is one of the greatest advantages of higher plants.
 
 

Animals

Our first specimen is clearly an animal bone.  There is no way that it could be alive.  Animals do not have any parts that can survive just lying around on their own.

How can we tell whether this is a living bone or a fossil bone of some extinct animal, which I just dug up in my back yard?  Bones of extinct animals are not common in Nashville, but are occasionally found in the river valleys.  A trained anatomist, would probably immediately identify it as the thigh bone of a chicken.  You could probably do the same if you could smell it.

Do any animals have the ability to put themselves in a dormant state to live through hard times?
