Description:
Algae are a very large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms, such as the giant kelps that grow to 65 meters inlength. Most are photosynthetic like plants, and "simple" because their tissues are not organized into the many distinct organs found in land plants. The largest and most complex marine forms arecalled seaweeds.
Algae exhibit a wide range of reproductive strategies, from simple, asexual cell division to complex forms of sexual reproduction.

Characteristics:

Algae lack the variousstructures that characterize land plants, such as phyllids (leaves) and rhizoids in nonvascular plants, or leaves, roots, and other organs that are found in tracheophytes (vascular plants). Many arephototrophic, although some groups contain members that are mixotrophic, deriving energy both from photosynthesis and uptake of organic carbon either by osmotrophy, myzotrophy, or phagotrophy. Some unicellularspecies rely entirely on external energy sources and have limited or no photosynthetic apparatus.
Nearly all algae have photosynthetic machinery ultimately derived from cyanobacteria, and so produceoxygen as a by-product of photosynthesis, unlike other photosynthetic bacteria such as purple and green sulfur bacteria. Fossilized filamentous algae from the Vindhya basin have been dated back to 1.6to 1.7 billion years ago.









Algae Uses:

Energy source
To be competitive and independent from fluctuating support from (local) policy on the long run, biofuels should equal orbeat the cost level of fossil fuels. Here, algae based fuels hold great promise, directly related to the potential to produce more biomass per unit area in a year than any other form of biomass. Thebreak-even point for algae-based biofuels is estimated to occur in about ten to fifteen years.
Fertilizer
Seaweed is used as a fertilizer.
Today, algae are used by humans in many ways; for example,...
