
Working with your partner from the Eukaryotic Cell Labeling
activity, research the cell organelle that has been assigned
you.
Specifically, you are need to know the key structures and
functions of your organelle.
Use the template titled, “Speed Dating Planning” to help
organize your information (this is on the back of your
Eukaryotic Cell Diagram Sheet).
This needs to be completed by the beginning of tomorrow’s
class.
Take on the persona of your organelle.

Pair With your organelle buddy:
 Your instructor will distribute slips of paper with a description of each organelle.
 Find the one that matches YOUR organelle and compare that description with the
ORGANELLE SUMMARY on your Speed Dating Planning sheet.
 If the descriptions are the same… you’re all set. If the descriptions are different,
use the description on the slip of paper to tell other organelles about yourself.
(4 min)
When you meet another organelle (3 minute rounds):
 Introduce yourselves and shake hands
 Find out each other’s jobs (1 min.)
 Find a connection between the two of you – how do your jobs relate? (1 min.)
 Record information in the Organelle Chart.

important jobs in living things, such as:



Form body structures (muscle, bone, hair, nails,
skin)
Act as enzymes to speed up chemical reactions
(like digestion) in our bodies
Act as hormones that send signals through the
bloodstream
[And many other things we’ll learn about later!]
