 The two pictures above show a paramecium and some plant matter/dirt that was obtained in the water outside Baxter Lecture Hall (the pools with lily pads right in front of the entrance to Ramo Auditorium) at 8 pm April 10, 2019. The sample was obtained by collecting the water into a tube (dipping the tube into the water and collecting the water as such).


 The domain is Eukarya, and this is a paramecium due to its oblong shape and the presence of a smaller, darker, circular structure in its center that is most probably a cell nucleus.

 The picture above shows a magnification of pollen collected from the Matilija Poppy from Caltech’s campus. The sample was obtained in front of Earle M. Jorgensen Laboratory (across from the Hameetman Student Center) off of St. Pasqual Street at 7:05 pm May 9, 2019 (pictures that show the sample’s location are shown below). The sample was obtained by using a cotton swab tip to scrape off the flower’s pollen from its anthers onto a glass slide, and then it was prepared for examination using tape and a cover slide.


 The Matilija poppy belongs to the genus Romneya, which has two species: Romneya trichocalyx and Romneya coulteri. Romneya trichocalyx is distinguished from Romneya coulteri by the presence of hairy sepals.Sepals are the part of a flower that protect it while it is budding, and this particular flower exhibited hairy sepals. Thus, this flower is the species Romneya trichocalyx.
