Life is a whim of several billion cells to be you for a while. ~ Author Unknown


“Z” is for zygote, as in the union of two separate cells, which form one.

A zygote (from Greek ζυγωτός zygōtos “joined” or “yoked”, from ζυγοῦν zygoun “to join” or “to yoke”), is a eukaryotic cell formed by a fertilization event between two gametes. The zygote’s genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual. (Courtesy of wikipedia.org)


Ironically, for the final letter in our A to Z Challenge, I’ve chosen something that denotes a beginning!

The zygote is created when the female gamete (ovum) joins with the male gamete (sperm) during fertilization. This process is the same for plants, animals and humans. 


It never fails to amaze me that a tiny cell, like those pictured above, can grow into the engineering masterpiece that the human body is – and all in nine short months!

Two of the most interesting and informative classes I ever took in college were Human Anatomy and Physiology. I came away with an entirely new respect for how so many different parts, that perform vastly different tasks, all function in complete symbiosis!

Now, if we could only get the finished human products to work together with this same level of synergy and collaboration. We could pool a vast amount of intellect and creativity for the good of the planet…just imagine the possibilities!!

Blogging From A to Z – Y

“Y” is for “Yesterday”, the title of the Beatles song, co-written by Paul McCartney and John Lennon, and performed by McCartney in the video below.

“Yesterday” was voted the best song of the 20th century in a 1999 BBC Radio 2 poll of music experts and listeners and was also voted the No. 1 pop song of all time by MTV and Rolling Stone magazine the following year. In 1997, the song was inducted into the Grammy Hall of Fame. Broadcast Music Incorporated (BMI) asserts that it was performed over seven million times in the 20th century alone.

Youth is another Y word that comes to mind when I think of yesterday. While the song is specifically about the breakup of a relationship, my memories of yesterday entail much more. Not only do they consist of my own childhood and growing up years, but those of my children, as well.
