Grade 8 Science - Cell Analogy
Your task is to demonstrate your vast knowledge of cell organelle function, structure
and size.
A Cellular Story
Time to put on that creative writing hat! You need to show off your understanding of
cell structure through story, a comic, a map, or any other ways you think would be
best! Use the story as a vehicle to explain the physical structure of each organelle,
how big they are compared to the other organelles and their function within a plant
or animal cell.
A few “off the top of my head” ideas:
 Your main character is adventuring inside a cell.
 Your main character is a doctor, trying to diagnose a patient with a cellular
problem.
 Your main characters are organelles, having some sort of “self-help group”
meeting.
Organelles:
 Cell wall (plant cell only)
 Chloroplasts (plant cell only)
 Cell membrane
 Nucleus
 Cytoplasm
 Golgi apparatus
 Ribosome
 Endoplasmic Reticulum
 Vacuole
 Mitochondria
 Lysosome

in a creative
way.
All of the
organelles are
used correctly.
A few may be
missing.
The functions of
all of the
organelles are
described
accurately and
with detail.
Ideas and
representations
are clearly
communicated
and can be
easily
understood by
others
The functions of
the organelles
are described
with some
detail.
The work looks
mostly neat and
professional.
There is one (1)
area that needs
work or
improvement.
