 This is an image of pond water taken from the Caltech turtle pond at 7:30. The sample was taken using a falcon tube. The objects in the image are most likely multicellular organisms. A question I have about the image is whether or not the organisms in the image feed on other organisms, or produce their own energy. An approach to answering the question would be to observe them for a longer period of time to see if they are capable of moving and consuming other organisms. #caltechbi1

 Description: Pollen grains in a fold scope slide. The dark specks are in focus, and the light specks are out of focus, but they are all pollen grains.


 Location and time: Flower taken from the Bechtel Residence courtyard at Caltech. Time: 9:00 PM. Date: 5/8/2019


 I picked a flower from a bush in the Bechtel courtyard. I brushed off pollen from the anthers of the flower using a toothpick, and placed the pollen on a slide. I then covered the pollen with a cover slip and taped it to the slide. Picture of how the sample was obtained:

 Plant species of the pollen: Aloe vera. This was determined by using the Pl@ntNet app to determine the species based on a picture of the plant.
