Literature review: Animal cells and plant cells have similarities and differences. In this lab, bacterial, animal, and Analysis. In this lab students observe Elodea leaves under magnification. The cell wall keeps plant cells from bursting. Overall, the onion skin cells (plant cells) are rectangular and are always with other plant cells and cheek cells (animal cells) are circular and are secluded from each other. Obtain a microscope and a whitefish slide. While both animal and plant cells have microtubule organizing centers (MTOCs), animal cells also have Biologists typically use microscopes to view all types of cells, including plant cells, animal cells, protozoa, algae, fungi, and bacteria. 01 Book: The Biology Corner (Worksheets) Cell Biology. A wet mount is used to observe living cells that are thin and transparent enough for light to pass through. specimen used to observe plant cells.

The cells of the human cheek lack a cell wall, as do all animal cells. The process of mitosis is only a short period of the lifespan of cells. c) Primarily, the onion cells are close together and all touch each other, while with the cheek cells, they are more spread out. Although cells may appear outwardly different, they resemble each other because they share common structures. Edit. 2. Animal cells tend to lack cell walls and chloroplasts, while plant cells do contain chloroplasts and have cellulose cell walls. Cheek cell drawing (any power but preferably high) Drawings, Conclusions and Questions: Onion Cell Label: Cell Wall Nucleus Cytoplasm Cheek Cell Label: Cell Memebrane Nucleus Cytoplasm Complete the following chart: The Cell organelle found in plant, animal, or both.
