Consider the characteristics of a living and a nonliving thing. Describe a few ways that the
two are alike and a few ways that the two are different.
Living Things have these characteristics:
Non-living things:
1. Made of cells - cell theory
2. Carbon based - organic
3. These three important parts .
*cell membrane (protection)
*DNA (genetic identity)
*ribosomes (for making proteins)
4. Absorbs energy from it's environment
5. Able to grow, change or mutate.
6. Possibility of death or to go extinct
1. Rocks are good examples
Accept all reasonable responses.
2. They Lack the characteristics of life mentioned earlier.
3. A Virus has many characteristics of life,
but it lacks ribosomes and cannot make it's own proteins.
Therefore it is NOT a living thing and it must hijack a cells
ribosomes to multiply.
4. With artificial intelligence, robots may someday
"come to life"
