The difference between the two students that we know of is that they used a different meter stick. So the difference would be best attributed to the different tools they used.
Note, this is quite a huge difference. It's likely that one of the sticks, or both, are quite defect.
For starters, the left image is a plant cell and the right image is an animal cell.
The black dots in both images would be drawn to the nucleus. All cells have nuclei. The black oval in the right image would be drawn to the cell membrane. Only animal cells have these. The rectangle with a gap would be drawn to the cell wall. Only plant cells have cell walls. The space surrounding the nucleus in both cells would be drawn to cytoplasm. All cells have cytoplasm. The dotted circles would be drawn to chloroplast. Only plant cells have these.
Hope I could help!
