Petals under direct light. Note the cellular structure visible on the edges
The images show petals from a purple flower (suspected to be lavender or lilac), under direct light (generated using a mobile-phone flashlight). The sample was obtained from the plantations behind Bechtel residence at Caltech’s campus (1200 East California Boulevard, Pasadena, CA) around 5:00 pm local time (CA) on May 8th, 2019. The flower was cut using a scissor, and the petal was flattened using a cotton swab.
Note the cellular structure visible at the edge of the flower petal, as well as, the gradient of density of cellular material.
