Keaton had a project for school, where he had to build a plant and animal cell. He figured out what he needed for a cell wall, membrane, nucleus, mitochondria, chloroplast, and a few other things. He found some little containers that became the cell wall. He found beads that had squiggles on it that would demonstrate the mitochondria. He filled the containers with water to show the cytoplasm. He had all the required cell parts accounted for. I thought he did a great job.
