Algal Groups
Microalgae are microscopic organisms that can grow via photosynthesis. Many groups grow quickly and are more productive than land plants and macroalgae (seaweed). Microalgae reproduction occurs primarily by vegetative (asexual) cell division, although sexual reproduction can occur in many species under appropriate growth conditions. Microalgae are efficient for fuel production and they are capable of taking a waste (zero-energy) form of carbon (CO2) and converting it into a high density liquid form of energy (natural oil).
There are several main groups of microalgae, that differ by pigment composition, biochemical constituents, ultrastructure, and life cycle. Five groups were of primary importance to the ASP: diatoms (Class Bacillariophyceae), green algae (Class Chlorophyceae), golden- brown algae (Class Chrysophyceae), prymnesiophytes (Class Prymnesiophyceae), and the eustigmatophytes (Class Eustigmatophyceae). The blue-green algae, or cyanobacteria (Class Cyanophyceae), were also represented in some of the collections.

Famous quotes containing the word groups:
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
