What are phytoplankton?
by David Herring
Phytoplankton are microscopic plants that live in the ocean.
There are many species of phytoplankton, each of which has a
characteristic shape. Collectively, phytoplankton grow
abundantly in oceans around the world and are the foundation of
the marine food chain. Small fish, and some species of whales,
eat them as food. Larger fish then eat the smaller fish. Humans
catch and eat many of these larger fish. Since phytoplankton
depend upon certain conditions for growth, they are a good
indicator of change in their environment. For these reasons, and
because they also exert a global-scale influence on climate,
phytoplankton are of primary interest to oceanographers and
Earth scientists around the world.
Phyto means Light and Plankton means Floating/Suspended.
Scientists at NASA theorize that some 3 1/2 billion years ago,
the world was changed forever. The appearance of tiny organisms
with the ability to convert sunlight, warmth, water and minerals
into protein, carbohydrates, vitamins and amino acids marked the
beginning of life. Phytoplankton, the single-cell plants are the
basis of all other life forms on planet earth, they are the
'vegetation' of the ocean. Phytoplankton are responsible for
making up to 90% of Earth's oxygen. Phytoplankton are the food
utilized by some of the world's largest and longest living
animals and fish. Blue Whales, humpbacks, baleen whales and more
all eat plankton and live between 80-150 years while maintaining
great strength and endurance and are sexually active until they
die.
Plankton have an alkaline pH, which is important, given the
acidity of our diets high in refined sugars, soda pop, and
farmed large animals. The high density of nutrients found in
algae is extremely important for many reasons. Perhaps the most
important (as noted above) is that these nutrients maintain
human cell membranes in structure and function. This is vital
for cell detoxification, and for the overall metabolism of human
cells. In fact, the causes of diseases have been simplified to
very specific mechanisms, all of which center on cell membrane
function and structure. Inflammation, Oxidation, Toxicity, and
Mitochondrial dysfunction keep cell membranes from doing their
job effectively. Algae contain high levels of antioxidants, and
anti-inflammatory micronutrients to fuel metabolism and
detoxification. Also, they stoke the fires of the Mitochondria,
where cells make energy required to carry out their function. Of
course, photosynthesis is the mechanism whereby plants in
general and algae in particular, harness life-sustaining solar
energy. (J. Applied Phycology 1993;5:235.).
Dr. Robert Rowe Ph.D. - "...Our beliefs are even
responsible for our genetic makeup. Your genes will change
to meet your beliefs. To understand this concept better,
read the book
Biology of Belief by Bruce Lipton. There is a lot of
solid scientific evidence to show that, on the smallest
level, we are actually made up of light and energy, which we
have at least some control over. And when we look at our
world from this viewpoint, there is so much more to see and
understand about its complexity, and it gives us more power
over our destiny.
Dr. Jerry Tennant, M.D. -
"One of those rare
products that contains almost everything you need for life
(and the rebuilding of a healthy life) is phytoplankton. It
contains the nine amino acids that the body cannot make and
must be consumed in our diet (essential amino acids). The
essential fatty acids are also present (Omega 3 and Omega
6). Vitamins A (betacarotine), 81 (thiamine), 82
(riboflavin), 83 (niacin), 85 (pantothenic acid), 86
(pyridoxine), 812 (cobalamin), C, and D (tocopherol) and
major and trace minerals are all present in phytoplankton.
In short, it contains almost everything one needs to sustain
life. Therefore, it contains almost everything one needs to
restore health by providing the raw materials to make new
cells that function normally. This is particularly true if
one stops putting toxic materials such as artificial
sweeteners and trans fats (partially hydrogenated fats) into
our body."
Glyconutrients
Marine Phytoplankton is a rich source of
glyconutriens which play an important role in
good cell-to-cell communication. "Most of
the Nobel prizes in Medicine and Biology have been awarded
to the concept of “cell communication,” which is how
our 100 trillion cells get their metabolic function
coordinated (J. Science, November 26th, 2004.) They do this
through a system of “messages,” which are well-known
molecules like hormones, neurotransmitters, enzymes, etc.
They form a vast network of communication, which should have
never been separated into different components. The Psycho-Neuro-Immune-Endocrine
system of cell communication to coordinate our metabolism is
now considered to be the cornerstone of health and function
in cutting edge research" Dr. Hugo Rodier (“The
intricate interface between the immune system and
metabolism,” J. Trends in Immunology 2004;25:193.)
Marine Phytoplankton contain many elements available no
where else. You may have heard of fresh water phytoplankton
like Spirulina and Chlorella. These algae also have many
health benefits, however, with the 200+ separate species of
marine phytoplankton, their nutritional profile is second to
none!

What Are Phytoplankton?
Source: NASA Goddard Space Flight

Phytoplankton (phyton =
plant; planktos = wandering) are small,
single-celled organisms that live in the sea. There
are approximately 10,000 species of phytoplankton.
They are characterized by size, shape, and
pigmentation.
We can observe phytoplankton with satellite
instruments via ocean color remote sensing,
primarily with the NASA Goddard Space Flight
Center's
SeaWiFS instrument and
MODIS instrument. The satellite detects
different concentrations of Chlorophyll a with ocean
color satellites. All phytoplankton have Chlorophyll
a and accessory pigment that are either
photosynthetic or photoprotective accessory
pigments. Phytoplankton convert sunlight into
biomass using a process called photosynthesis.
During photosynthesis, phytoplankton use solar
radiation, water and carbon dioxide to yield glucose
(a carbon form of energy they can utilize) and
oxygen.
Overall Equation of Photosynthesis:
6CO2 + 12H2O + sunlight -> C6H12O6 + 6O2 + 6H2O
Phytoplankton and other plants use glucose as
"building blocks" to grow. Also, through
photosynthesis, these microscopic marine plants
nourish the entire marine food web.
Finally, phytoplankton are essential because they
are a critical part of the ocean biology and in part
control the level of carbon dioxide in the
atmosphere.

Over the past two
decades, satellites have been measuring
the color of the oceans. Seawater
changes from blue to green as the
abundance of phytoplankton in the water
increases. Researchers have used this
phenomenon as recorded in the satellite
color data to determine the total
quantity of phytoplankton in the world's
oceans. |
