What is cell?
A cell is the smallest functional and structural unit of all living unit of all living organisms.
What is an organism?
An organism is any living thing.
What are all organisms made up of?
cells
What happens if a cell gets too large?
The cell’s surface area will not be large enough to take in enough nutrients or pump out enough waste.
What are the three basic characteristics of all cells and organisms that the cell theory lists?
All organisms are made up of one or more cells. The cell is the basic unit of all organisms. And all cells come from existing cells.
What are organisms that are made up of just one cell called?
Unicellular.
What are organisms that are made up of more than one cell called?
Multicellular.
What do cells in multicellular organisms do?
They have specialized functions.
What do cells in unicellular organisms do?
They must carry out all of the functions for life.
What is the cell membrane?
a protective layer that covers a cell’s surface and acts as a barrier between the inside of a cell and the cell’s environment.
What is cytoplasm?

What is a prokaryotic cell?
is a single celled organism that does not have a nucleus or membrane bound organelles (DNA is located in the cytoplasm).
What organisms have prokaryotic cells?
Bacteria and archaea, they are smaller than Eukaryotic organisms.
What are Eukaryote?
