Is Chlorella an Effective Food Supplement?
Chlorella is single-celled green alga which is placed under the phylum Chlorophyta. It is spherical, without flagella and about 2-10 um in diameter. Chlorella bears a green pigment for carrying out photosynthesis known as chlorophyll. The chloroplast bears chlorophyll a and b. With the help of photosynthesis it multiplies rapidly and requires only carbon dioxide, water, sunlight and little amount of minerals for reproduction. Chlorella has derived its name from a Greek word chloros which means green. Since it lacks sexual cycle in its life history genetic studies are not possible in these algae so researches have declined the use of these algae as an experimental model in the recent years.
