Help with cell analogies please!?

Question

So i need it by tomorrow, and i already got 13 of them. just 2 more left... they are:
1. cytoplasm/cytosol
2. chloroplast/plastid
i need to relate them with an amusement park w/ reasons why it is. For example:

A mitochondria is to a cell just as the vending machine is to an amusement park. Just as the mitochondria provides ATP by using sugar, fat, & oxygen to power the cell. The vending machine uses food to power the employees to work at the amusement park.

Answer 1

I like the vending machine analogy.

I'd say the open area is the cytoplasm. It's there to provide a space for everything to move around in and a medium for interaction.

The chloroplast would maybe be big solar powered vending machines? The chloroplasts use light to convert ADP + P to ATP. In an animal cell, the vending machine would be as you said above. In a plant cell, the vending machine would take in light and dispense snacks, but then some of those snacks would be eaten, and some stockpiled as sugars for later (nighttime) use in more conventional vending machines (if I'm making any sense at all).

For the cytoskeleton, I'd say the roller coaster. It has structural support and helps hold the cell together, but also provides a highway that carrier molecules (like some types of myosin) can zip along carrying packages to different destinations.
