12/16/10 Science

Today in class we started out watching a video of a cell. We had to take notes on a few questions. 1: What do you see? 2: Is it living or nonliving? 3: What kind of cell is it? 4: Is it single or multi-cellular? My answers were, 1. I saw something moving on a surface. It kept bumping into brown rusty colored things. It looked like the thing was eating them. The thing had a clear outer layer that looked like it was keeping it's parts together. The inside was brown and it spiraled to move. It had hairs too called cilia. 2. I said it was living because it looks like it has the characteristics from what I saw in the video. 3. It has cilia so it's an animal cell. There are compartments and a nucleus so it's a eukaryotic cell. 4. It is single celled because there was only one nucleus. After that, we watched another video to prove some points. It was a video of the same type of cells eating yeast that was dyed red. Below is a video of an animal cell I thought was interesting.

  1. Just because it has one nucleus does no mean it is single celled. Parameciums have two nuclei, but it is single celled.
