Introduction: The cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In other words, without cells we would not be able to live or function properly. There are animal cells and plant cells. The other day in biology class we studied the animal cell. We were divided into groups and each of us chose a different slide of animal cells to observe. My group chose the slide,'; Smeared frog blood';.The animal cell is slightly different from the plant cell for only a couple of reasons. One is the fact that the plant cell has a cell wall and the animal cell does not. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as the control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the cytoplasm. This is the watery material found inside the cell between the cell membrane and the nucleus. The cytoplasm also contains organelles, which have specific functions in cellular metabolism. Then there are the Golgi bodies, which serve for the processing, packaging and storage of the cell. These organelles package and ship things. Another part of the cell, very important in fact, are the lysosomes. These organelles are used to break down objects and contain enzymes. Method: We first placed the slide under a simple microscope and observed it at a tenfold magnification level. We each took turns watching. We then copied them as drawings into our Cornell notebooks. We then changed the magnification to fifty times and looked at the slide. We each took turns watching. We then copied what we saw into our Cornell notebooks. Next we changed the magnification level to sixty times and each of us took turns looking at the slide. We then copied what we saw into our Cornell notebooks and sat together. When we finished drawing we talked about what we saw and exchanged ideas on how to write our lab reports. Conclusion: In conclusion I noticed that without cells we would not be able to function or even without the cell theory because we would not know how to cure our body and our cells.
