Today, I was in my advanced biology class and we were viewing slides we had made of our cheek cells. My biology teacher told us a story about the first year he had been teaching. A girl had made a slide of her cheek cells and had abruptly exclaimed "Mr. Barner! One of my cheek cells is moving!" He had gone over to investigate and discovered that the moving cheek cell had been a sperm. He had to leave the room. MLIA
