what we did in class this week 11/6/09

This week in class we further discussed animal and plant cells. Last week in class we did an experiment involving cheek cells. after the experiment we were curious to know whether cheek cells were animal or plant cells. After researching them we found out that cheek cells were animal cells for two reasons. The first reason being that cheek cells come from humans and humans are animals. The second reason being that cheek cells had the same cellular structure as an animal cell. Another thing we did was research the different organelles in plant and animal cells. An organelle is a like a tiny organ in a cell.After doing this experiment we were wondering what were the differences between animal, plant and bacteria cells so we made a triple Venn diagram to compare the three cells an we came up with many similar and different things for all three of them.

The last thing we did this week was an experiment with Paramecium. Paramecium is an organism found in pond water that we found in the pond water experiment for the sick students at Jackson and Truman Middle Schools. So we looked at pond water to find Paramecium and after we did we did some more research and found out that Paramecium is neither a plant nor an animal cell.
