In this post I’ll be talking about cells and their various functions. A variety of cells exist in the human body from skin cells to blood cells, they maintain, protect and repair the body. This post will cover the chugach standards 9.4-9.5, which asks about cell process and functions of the cells organelles.
There are two major cell categories, these are Eukaryotes and Prokaryotes. Eukaryotic cells are found in multicelled organisms like humans or plants. Where as Prokaryotes are single celled organisms like bacteria. In this post I’ll be focusing on Eukaryotic cells.
Within the Eukaryotic category there are two general sub-categories: animals cells and plant cells. These cell are mainly separated by one difference, plant cells have a cell wall that differs from the animals cells cell membrane. This is the most easily seen difference between the two cell types.
Using humans as an example, we can see that there are hundreds of different types of cell that exist within the body, some example are blood cells, white blood cells, skin cells and brain cells. There’s a general structure that is consistent in all animal cells.
The general animal cell contains roughly 14 different organelle. These help the cell reproduce, store organic molecules and process the organic molecules into ATP (energy for the cell). Generally they function similar to a humans bodies organs, allowing them to survive and complete their specialized tasks.
These organelle are:
What are cells general functions? Well I’ve determined that there are three main jobs that the cells do/can do. The first is the ability to let various organic molecules pass through their cell membrane to process the molecules and turn them into ATP for energy. This allows them to produce proteins to replace degrading or exported proteins and reproduce. Cells can also reproduce themselves by copying their DNA to two new cells creating an exponential growth pattern.
We’ll be using Minecraft in creative mode (You can check out my minecraft guide here) to create a semi-interactive model of a cell in Minecraft. Basically the students will learn about the structure, and functions of animal cells and even plant cell, if you’d like, and then convert that knowledge into a 2d model of a cell. As an example you can check this world save out of a plant cell.
- I’m going to start placing challenges for each task I give. So for this one
- Challenge one:
- Create a plant cell, animal cell and prokaryotic cell.
- Challenge two:
- Make the model 3d, heh, so basically check out real 3d models of cells and see if you can replicate it.
- Challenge Three
- Animate the ingame model with the functions of the cell.
- This isn’t an easy challenge and I couldn’t do it myself. I’d imagine that using redstone and some advanced game mechanics.
- A friends Minecraft creations, he has some tutorials but mostly look at his creations channel, their pretty informative. Here
- Redstone rules
- (Editors note: redstone is pretty complicated stuff to mess with considering the rest of the game’s mechanics are… simple. So this is a very hard task and would rate “super, super, advanced” in the rubric)
Also as a note, this project should be done with a group, especially building the Cell in minecraft.

Minecraft Cell model
|
Model is missing several organelle and they were placed in the wrong areas of the cell.
|
Model has all of the organelle but a few or all are placed in the wrong position of the cell.
|
Model has all of the organelle for each cell type they’re all in the correct position and even labeled but are only in 2D.
|
The model has all of the correct organelle, they’re in the proper position and all are labeled. It is in 3D and scaled so you can walk through the cell and see each part of the cell as if you were on a tour.
