Description:This 1971 image depicted a frontal view of a Petri dish culture in which a small coloney of Chlorella algal organisms had been cultivated.
The genus Chlorella is composed of members of single-celled microalgae containing high amounts of both chlorophyll-a, and chlorophyll-b, and is therefore, very photosynthetically efficient. Note the very dark-green, almost black coloration of the single chlorophyll-rich colony.
