Lemna lab reportLemna minor, sometimes commonly called lesser duckweed, is perhaps the most wide-spread of the duckweeds, being found throughout the world. It is native to Missouri where it typically occurs in sloughs, ponds and slow-moving streams throughout the State (Steyermark). It is called duckweed because ducks (as well as other waterfowl) like to eat it.Lab Reports Each student will prepare a lab report for each of the two experiments conducted in lab (the Lemna and Vermiculture studies). There will be time allocated in lab for hypothesis generation, data collection, data summary and graph preparation. Students will work INDEPENDENTLY on the lab report, which will be submitted to turnitin.com.Plants maintained at 17 or 22°C did not become infected. The results from the pond and laboratory work showed that high plant density and temperature above 24°C were necessary for infection, and infection takes place by hyphal elements that spread in the water.
