This diversity is reflected in characteristics related to cell motility, light harvesting ability, ultrastructure, cell wall, among other things.
These organisms are termed “autotrophs” since they are able to convert inorganic carbon to organic carbon without using preformed organic matter as an energy source.
Remember, “heterotrophs” (such as animals) use organic matter formed by autotrophs as a food source Until the 1970s it was thought that the most abundant and Until the 1970s it was thought that the most abundant and important phytoplankton were the larger ones. More recent research has shown that the very smallest (the size of bacteria) and most primitive phytoplankton, the CYANOBACTERIA, are most important in photosynthesis (shown are larger species). Phytoplankton can be divided into Phytoplankton can be divided into two main groups, the prokaryotes and the eukaryotes
• The prokaryotes are the cyanobacteria (also called blue green algae) • The eukaryotes are the more highly evo...
