What is the smallest unit of life that can carry out all life processes?
Cell
What term describes an increase in size or number of cells?
Growth
Which type of cell does not have a nucleus?
Prokaryotic cell
What are specialized structures inside cells called?
Organelles
Are viruses considered living?
No
What scientific idea states that all living things are made of cells?
Cell Theory
What sign of life allows organisms to react to their environment?
Response
Which type of cell does have a nucleus?
Eukaryotic cell
What molecule contains genetic instructions for how a cell functions?
DNA
What key characteristic of life do viruses lack?
Cells / metabolism
What term means “made of one or more cells”?
Cellular
What sign of life allows organisms to produce new organisms?
Reproduction
Where is DNA found in a prokaryotic cell?
Floating freely in the cell
What molecule helps make proteins and carry genetic instructions?
RNA
Why can viruses not carry out metabolism on their own?
They need a host cell
Why does cell theory explain why viruses are not living?
Viruses are not made of cells
What process allows organisms to obtain and use energy?
Metabolism
What structure stores DNA in eukaryotic cells?
Nucleus
Why are organelles important to cell survival?
They perform specific functions
What genetic material can viruses contain instead of DNA?
RNA
Explain why cells are considered the basic unit of life.
They perform all life processes
List all six signs of life.
Cellular, metabolism, growth, response, reproduction, homeostasis
Compare prokaryotic and eukaryotic cells using two differences.
Nucleus present vs absent; complex vs simple
Explain how DNA and organelles work together in a cell.
DNA gives instructions; organelles carry them out
Justify why a virus is not an organism using two reasons.
Not cellular; no metabolism
