What is a limitation of Jillian's cell model?
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.
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.
