Doctor Garland - a notorious 'quack' physician - is deliberately misleading the public by labelling Chlorella as 'Marine Phytoplankton' ... a completely false statement! However, he contradicts himself in his marketing blurb by describing Chlorella as a 'fresh-water algae' which of course is TRUE.
Chlorella is not an ocean derived (salt water) plant, therefore it is not marine phytoplankton, which means he is promoting a scam. See below for the true definition of marine phytoplankton.
Mass produced chlorella powder costs very little to manufacture compared to genuine DNA Verified Nannochloropsis gaditana. If you are interested in purchasing over priced, fake phytoplankton, then visit Dr Garland's web site.
Marine Phytoplankton are microscopic floating plants, mainly algae, that live suspended in bodies of water that drift about because they cannot move by themselves or because they are too small or too weak to swim effectively against a current... Phytoplankton live near the surface of the ocean because they need sunlight like all green plants. They also need water and nutrients to live. Phytoplankton use water and CO2 to grow, but phytoplankton still need other vitamins and minerals - like iron - to survive. Phytoplankton are at the base of the food chain. So, when the population of phytoplankton is reduced, almost the entire food chain suffers.
Microalgae were among the first life forms to appear on our planet. Among them, some unicellular organisms are particularly minute and form the picophytoplankton group. The term phytoplankton comes from the Greek words “phyton” meaning plant and “plagktos” meaning wandering, because these organisms are taken along marine currents. The prefix "pico" probably comes from a Spanish word which means "tiny". The picophytoplankton consists of both evolved organisms, called "eukaryotes", which have well-defined nuclei and organelles (such as mitochondria or plastids) and more primitive organisms, called "prokaryotes", in which the cell components (DNA, ribosomes, membranes, etc.) are not separated into defined compartments. There are three principal eukaryotic phytoplankton groups that came to dominate the modern seas: dinoflagellates, coccolithophores and diatoms.
