Eukaryotic Cells Part 1: Animal Cells and Endosymbiotic Theory
Prokaryotic cells were simple enough, but eukaryotic cells are much more complex! They have so many more little features and compartments, like the deluxe model of your car. We have to learn about every single one of these organelles and...

Eukaryotic Cells Part 2: Plant Cells
It's not just animals that are made of cells, it's plants too! Plant cells are very similar to animal cells, but they have some stuff that animal cells don't, like chloroplasts, that allow for photosynthesis. Let's take a tour through a...

Structure of the Cell Membrane - Active and Passive Transport
What is it that separates what's inside a cell from what's outside of a cell? Why, that's the cell membrane. What's it made out of? How does it work? How do molecules get in and out of the cell? These are super-important concepts! Let's...
