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.

B. It does not show the functions of the cell parts

Explanation:

Cell models will always have some limitations. Here, the limitation is that Jillian did not include the functions of the cell parts, which can be confusing for someone on the outside who comes to take a look. So, the answer is B.

Choice A doesn't really make sense at all.

Obviously, the cell model is larger than a real animal cell, but that's the point of models - they are created to help scientists better understand and visualize very tiny things. Eliminate C.

This cell model is definitely not more complex than a real animal cell. If anything, it's more simplistic, so D is wrong.

Hope this helps!
