The Giant Plant Cell
The Case of the Giant Plant Cell
INFORMATION: The Giant Plant cell is roughly shaped like a cube with each side being
3 meters.
OBJECTIVE:
1. Research the structure and function of your chosen organelle
2. Calculate (using ratios) the dimensions of your giant organelle so it is proportioned to the scale of the
Giant Plant cell.
3. Produce an architectural blueprint with a description of your organelle construction (materials, size,
shape etc.).
4. Construct your approved design.
5. Prepare a class presentation (max. 5 min.) Focus on the structure and it’s functional contribution to
the plant cell.
EVALUATION:
Your organelle will be judged according to the accuracy of its size, and structural accuracy, creativity and
your presentation of the function.

Grading Rubric for Colossal Plant Cell Organelle
Basic Requirements
A. Construction of Organelle
o All constructed organelles must be 3-dimensional.
o All organelles must show internal and external details.
o All organelles must be the correct size for the colossal plant cell.
B. Oral Presentation
o Reports should be about 3-5 minutes long.
o Each member of the team should do part of the presentation.
o The presentation should include details about the organelle's structure and function.
o The presentation should include a discussion about how many of the organelles will
be manufactured for the colossal plant cell.
o The presentation should also include an explanation of the actual and giant size of the
organelle.
