Scattered light exposure on the pollen grains. Note the structure of the grains.
Direct light exposure on pollen grains. Note the distinct yellow-greenish color observed.
The images show pollen grains of an Orange Hibiscus flower, under direct and scattered light (generated using a mobile-phone flashlight). The sample was obtained from the plantations outside Page House 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 pollen grains were extracted using a cotton swab.
From observations of the flower structure (notably the stigma), the plant species is Hibiscus rosa-sinensis ‘Orange’ , a member of the Plantae kingdom. A significant feature to observe in these pictures is that the grains are oval-ish and yellowish green, with pointed edges.
