The Age of Discovery, Chapter 14: A Nantucket Sleigh Ride
1430 hours...
To our great delight, Lyra
discovers a single greenish cell wedged firmly in the ship’s rudder assembly –
the strange malfunction of our steering and elevator systems now
demystified. When she attempts to
free the organism with a length of hemp line the protist takes her on a merry
jaunt as she grasps the tether with all her strength.
“And there she goes!” reports Gyro,
as Lyra and the green beastie streak past the windows of the wheelhouse,
looking for all the world like a micro-scaled reenactment of a nineteenth
century Nantucket sleigh ride.
“Let go, Lyra, for heaven’s sake!” he shouts in vain at the drama beyond
the glass. “Why doesn’t she just
let go?”
“Because that simple and elegant
solution,” I mutter, “would be far too convenient! I suspect that our young biologist has reckoned that the
organism is worthy of closer study – and once she sets her mind to such a
task…”
“All well and good,” raged the concerned
and exasperated pilot, “but it’s carrying her farther and farther away!”
So as not to lose my prize
naturalist, I devise a quick plan to lure the green cell back to the Cyclops, and get it close enough for
capture.
As if reading my mind, Gyro offers
a timely recollection: “Skipper, remember the green paramecium, how it would
move out of our shadow to bask in the sunlight.”
“By Jove, ensign,” I proclaim, “we
will yet make a naturalist out of you!”
My mind was racing.
We had only just recently observed how hungry these organisms are for
light.
I turn to the ship’s controls and
power up the external lamps. Sure enough, as I had hoped, the organism changes
its mad course and heads toward the light, towards the ship, and safety for
Lyra!
1515 hours...
Lyra is now safely aboard the Cyclops again and our new mascot – the
green algae cell – is being observed in a glass enclosure. It has the usual
characteristics of a single cell: a roundish clear body filled with cytoplasm.
This one has two flagella, which it uses like propellers for moving about. Each
flagellum joins the body where we observe a cluster of red granules. We suspect
this red “eye spot” is sensitive to the presence of light, and steers the cell
by sending chemical signals to the flagella. Also inside the cell is a nucleus,
a number of whitish starch bodies, and most predominantly a horseshoe-shaped
green structure – the organism’s chloroplast.
The chloroplast seems to be the
center of a great deal of biochemical activity within this organism. When light is shined upon the
chloroplast the oxygen levels in the tank begin to rise and starch bodies are
produced. Lyra believes we are watching the process of photosynthesis as it
occurs. She also suggests that a small menagerie of these organisms might serve
us by producing all the oxygen we could ever need! It appears that a happy
accident has provided us with a solution to our oxygen problem.
As we continue our mission I am in
awe. We have observed that every green cell in this life-rich world is a living
factory, producing oxygen and the molecules for life. It is here in the micro
world, I humbly realize, that the foundations of the living world begin!
