● Provide students broad examples of what can be understood from light microscopy of cells.
● Micrographs were all taken at 400X magnification, and each image demonstrates different cells and cell components.
● Set is an excellent complement to the Dynamic Cell Models (Z50569M, Z50571M) for classrooms short on microscopes.
● Each 16 x 20 poster comes in a sturdy frame with a grommet for hanging.
● A dry-erase marker may be used and erased on the frames.
● Set of five posters include: Elodea canadensis: These plant cells can be used to see cell walls, cell membranes, chloroplasts, and cytosol.
● Some nuclei are also visible.
● The central vacuole is apparent when viewing live cells as the area avoided during cytoplasmic streaming.
● These cells are unstained.
● Cheek (with bacteria): These human (animal) cells can be used to view cytoplasm, nuclei, and cell membranes (only as the edge of the cytoplasm).
● These can also be used to show that animal cells lack cell walls.
● The methylene blue stain used on these cells also reveals bacillus and coccus bacteria stuck to the cheek cells and slide.
● Red pepper: These plant cells are from the peel of a red pepper, which is a very tough portion of the fruit.
● Therefore, these cells demonstrate a particularly thick cell wall.
● Also visible are the red chromoplasts and plasmodesmata running through the thick cell walls.
● Some nuclei are also detectable, although these cells were not stained.
● Banana cells: These plant cells were taken from the fruit of the banana.
● The cells were stained with iodine to reveal the starch contained within their amyloplasts.
● The cell walls (very thin), cell membrane and cytoplasm, and amyloplasts are visible.
● Red onion: These plant cells were taken from the thin purple layer of a red onion.
● They were coverslipped in iodine to add some contrast to their nuclei, but no starch is present.
● The cell walls, cytoplasm, and nuclei are visible.
