Observing Plasmolysis / No Foldscope? No Problem!
1. In the space below, insert three photographs: one of each of the three red
onion cell ‘treatments’ described in the online content for the lab.
All photos should be taken by you. For photos inserted into this document, reduce the file size to tens or hundreds of kilobytes (there are a range of webbased tools and apps that can resize an image for you). It is okay to use the optical zoom on your device if doing so improves your image and allows you to see
the cell better – for this lab, your photo does not need to include the entire field of
view.
In addition to inserting the photos into this document, post your foldscope photos
to the BIOL 1020 Padlet Gallery as instructed in the online content for this lab.
Feel free to “like” and comment on other posts!
