I need help with this biology assignment. All about cells

For our assignment we had to draw out our vocabulary words:
Cell Wall
Chromatin
Nucleolus
Ribosome
Cytoplasm
Endoplasmic Reticulum
Golgi Apparatus
Vacuole
Lysosome
Chloroplast
Chlorophyll
Mitochondria
Cytoskeleton
Microfilament
Cilia
Flagella

The point of the assignment is to draw out the words. Not draw what it looks like, but draw how it functions relating to real life things. For example, for cell wall I drew a brick house with windows and for chromatin i drew an instruction booklett. I can't seem to figure out examples of what to draw for the rest of them! Help please? It would be much appreciated. Thanks so much!

Here are a few ideas:

Nucleolus - coal mine
Ribosome - An Spanish-English Dictionary (they translate mRNA into protein)
Cytoplasm - an empty basketball court (it provides an environment for everything to occur)
Endoplasmic Reticulum - an assembly line
Golgi Apparatus - FedEx truck
Vacuole - an attic or a moving truck (vacuoles both store and transport things)
Lysosome - garbage disposal
Chloroplast - a bakery (it makes food for the cell)
Chlorophyll - solar panel
Mitochondria - a power plant
Cytoskeleton - A human skeleton
Microfilament - Legos (they can be easily disassembled and reassembled in pretty much any shape the cell needs)
Cilia - A viking ship with lots of oars sticking out the sides
Flagella - the previous answer of a helicopter blade is good.

for flagella you could draw a helicopter propeller.
