Term
| Living organisms consist of: |
|
Definition
one or more cells
contain genetic information
use genetic information to reproduce themselves
are genetically related and have evolved
can convert molecules obtained from their environment into new biological molecules
can extract energy from the environment and use it to do biological work
can regulate their internal environment |

Definition
cells are the basic structural and physiological units of all living organisms
cells are both distinct entities and building blocks of more complex organisms |
|
|
Term
|
Definition
All cells come from preexisting cells
All cells are similar in chemical composition
Most of the chemical reactions of life occur in aqueous solution within cells
Complete sets of genetic information are replicated and passed on during cell division
Viruses lack cellular structure but remain dependent on cellular organisms |
