The document makes comparisons between structures and processes in cells to familiar objects and roles. It compares the nucleus to a king ruling a kingdom, ribosomes to cooks making energy-providing food, the smooth endoplasmic reticulum to highways helping transport, the vacuole to a cabinet storing food and water, lysosomes to soap keeping things clean, cytoplasm to water filling a space, the cell wall to walls protecting and shaping a plant cell, the cell membrane to police restricting entry, and the Golgi apparatus and chloroplast to entities that check/deliver essential items or make food, respectively.

3. Just like a king rules a
kingdom...
...the nucleus rules
a cell.

4. Just like a cook makes
food that gives you
energy...
...in a cell, ribosomes make
proteins that give you
energy.

5. Just like a highway helps
cars get places...
...in a cell the smooth
E.R. helps ribosomes get
to where they need to
go.

6. Just like a cabinet
stores food in your
kitchen...
...the vacuole stores food
and water for a cell.

7. Just like soap helps
keep you clean...
...the lysosome keeps a cell
clean.

8. Just like water fills up
a pool...
...the cytoplasm fills
up a cell.

9. Just like walls protect
and give your house
its shape...
...the cell wall
protects and gives a
plant cell its shape.

10. Just like policemen help
make sure that bad guys
don't get into places...
...the cell membrane
makes sure that only
things that a cell
needs can get in.

11. Just like you check,
wrap and deliver the
‫ משלוח מנות‬on Purim...
...in a cell, the Golgi
apparatus checks, fixes
and delivers proteins to
where they need to go.

12. This last one is only
in plant cells. Just like
your Mommy makes
food in a kitchen...
...the chloroplast is
where a plant cell makes
food for the plant.
