PHIL Image 8729

ID#:8729
Description:Under a high magnification of 1648x, this scanning electron micrograph (SEM) revealed some of the morphologic ultrastructure displayed by a number of pollen grains found within the dehisced, or split open, anther of a yellow "Fireworks" sundrops, Oenothera fruticosa flower. These pollen grains were of the "tricolpate" type of pollen, which means that their outer surface was traversed from pole to pole, by three symmetrically placed furrows. The textured surface also identified these grains as the "reticulate" type. Note the round shape of these grains, indicating that they had yet to undergo a drying process, in order to become ready to be disseminated into the plants environment.

The anther is the organ housed inside a flower that produces pollen through a process known as meiosis, which involves cell division that gives rise to a half compliment of chromosomes, known as haploidy. The anther resides at the distal tip of the "filament", both structures comprising the male portion of the flower known as the stamen. When a pollen grain representing a male gamete of a plant with its haploid chromosomal contents comes into contact with an ovum, or egg of that specie of plant, which also contains a haploid chromosomal compliment, a zygote is created containing a full compliment of chromosomal DNA.
