The unicellular forms are known as microalgae where as the multicellular forms comprise macroalgae.
Microalgae comprise a vast group of photosynthetic, heterotrophic organisms which have an extraordinary potential for cultivation as energy crops. They can be cultivated under difficult agro-climatic conditions and are able to produce a wide range of commercially interesting byproducts such as fats, oils, sugars and functional bioactive compounds.
Seaweed is a loose colloquial term encompassing macroscopic, multicellular, benthic marine algae. The term includes some members of the red, brown and green algae. They are photosynthetic, like plants, and "simple" because they lack the many distinct organs found in land plants. For that reason they are currently excluded from being considered plants.
The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. Almost all the algae are eukaryotes and conduct photosynthesis within membrane bound structure called chloroplasts. Cyanobacteria are organisms traditionally included among the algae, but they have a prokaryotic cell structure.
Algae are an extremely important species. For one, they produce more oxygen than all the plants in the world, put together! For another, they form an important food source for many animals such as little shrimps and huge whales. Thus, they are at the bottom of the food chain with many living things depending upon them.
With the recent research and interest into using algae for producing Biodiesel they have the potential to become even more important.
Algae - A source of biofuel
Algae as a source of Biofuel posses certain advantages.
Algae produce oil, and because of their growth rate and yields, they could produce a lot more than other energy crops. Some estimates suggest that microalgae are capable of producing up to 15,000 gallons of oil per Hectare a year. This could be converted into fuels, chemicals and more.
Microalgae, specifically, possess several attractive characteristics in the context of energy and biofuels:
- They provide much higher yields of biomass and fuels, 10-100 times higher than comparable energy crops.
- They can be grown under conditions which are unsuitable for conventional crop production.
- Microalgae are capable of fixing CO2 in the atmosphere, thus facilitating the reduction of increasing atmospheric CO2 levels, which are now considered a global problem.
- Algae biofuel is non-toxic, contains no sulfur, and is highly biodegradable.
