This week in AP Biology we did the mitosis and meiosis lab. As I previously discussed in my last blogs, mitosis which is when two genetically identical diploid daughter cells are produced and meiosis is the process which produces four genetically different haploid daughter cells. To began this lab we modeled mitosis and meiosis. We then prepared garlic for another activity. After following that we looked at onion root and fish egg cells to locate cells in the various stages of mitosis. We then proceeded to prepare the garlic root tip squash lab. In this part of the lab we took the garlic we had previously prepared by putting it into a sand and water mixture and placing it into a dark drawer, and cut off around 2 mm of the root tip. After that we put the root tip and hydrochloric acid on a slide and passed it through an open flame for five seconds. Then we put a chemical that was bright pink and fuchsia in the name on the slide and passed it over an open flame for 2 minutes. We then squished the root tip and put it under a microscope to see if we could locate cells in the various stage of mitosis, but unfortunately we were unable to. That then concluded the lab.
(I will publish pictures separately.)
Good blog. I wish you would have added your model pictures from lab.
