AP Biology Edible Cell Model Extra Credit Project –
Tuesday, January 4th, 2016
 The challenge is to create the most accurate edible cell for extra credit.
 The edible cell models must comply with the attached rubric. The goal is to create the most accurate
model of a plant OR animal cell in terms of structure and be able to identify and describe the function of
each structure when asked by the teacher.
 Rules for Model Preparation
1. The model must include all of the structures listed below and all materials used must be completely
edible.
2. The model must be three dimensional. In other words, it CANNOT be a flat icing drawing on top of
a cake. However, cake can be used as a construction material.
3. You must be able to identify each organelle on your model and describe its function without any
notes during judging.
4. The organelles should NOT be labeled on the models.
5. The following organelles must be included in your model to receive full credit for the project.
Cell Parts to be included in the Edible Cell Project

The Rubric
SCORES
Accuracy of
Model
Creativity
Knowledge of
Functions
3
Has all required 13
cell parts for an
animal cell or 15
cell parts for a
plant cell.
Highly Creative –
unique ideas,
colorful, high
attention to detail
2
Has 9-12 cell parts
for an animal cell
or 11-14 cell parts
for a plant cell.
1
Has 6-8 cell parts
for an animal cell
or 8-10 cell parts
for a plant cell.
0
Has 5 or less parts
for an animal cell
or less than 7 parts
for a plant cell.
Somewhat creative
– average ideas,
colorful, some
attention to detail.
Lacks any form of
creativity.
Knows all the cell
parts and their
functions.
Knows 9-12 cell
parts and their
functions for an
animal cell or 1114 cell parts and
their function for a
plant cell.
Limited Creativity
– not much
attention to detail,
parts are not
distinctive, limited
originality.
Knows 6-8 cell
parts and their
function for an
animal cell or 8-10
cell parts and their
function for a
plant cell.
A score 8-9 will earn the student 2 extra credits points on the marking period grade.
A score of 5-7 will earn the student 1 extra point on the marking period grade.
Any score below 5 will not earn any extra credit.
Only knows half
or less of the cell
parts and their
functions.
