Jillian made a model of an animal cell. She used a round balloon to represent the cell membrane. She pushed objects like marbles and rocks into the balloon to show cell parts, then filled it with water to show fluid inside the cell.

What is a limitation of Jillian's cell model?

It does not make up the tissues of a living thing.
It does not show the functions of the cell parts.
It is larger than a real animal cell.
It is more complex than a real animal cell.
