Plant Cell Lab- Virtual Images
In a lab, the students cut an onion and removed a tiny portion of the inside where cells can be viewed. To
make it easier to view the cells and the nucleus, a drop of iodine was placed on the slide. Normal onion cells
are clear (or white) but the ones pictured are orange due to the iodine stain. Use these images to complete
the Plant Lab.
On the onion cells, the cell walls divide individual cells. Each orange dot you see is actually a nucleus. A single
slide view on low power can show dozens of cells

The green dots you see are actually chloroplasts. Play the
video and you can see them move throughout the cell - a
phenomenon called "cytoplasmic streaming".
The nuclei of the plant cells here are difficult to see
because the chloroplasts take up so much space in the
cell. On the image above, the nucleus in two of the cells is
seen as dark blobs in the center.
