Abstract
Algae are photosynthetic organisms that occur in most habitats, ranging from marine, brackish water, freshwater to desert sands and from hot boiling springs to snow and in polar ice. Around 7000 species of red algae, 2000 species of brown, 1800 species of green and 1500 species of blue green are recorded so far. They vary from small, singlecelled to complex multicellular forms.The microscopic algae are called as phytoplankton whereas large benthic algae are called as macroalgae or seaweed. The life history of algae is complicated, and this is what really differentiates them from plants. In fact, macroalgae can pass through life stages so distinct that, in the past, they have been mistaken for separate species. Algae are found in the fossil record dating back to approximately 3 billion years in the Precambrian. Some of the algae like giant kelps of the eastern Pacific that grow to more than 60 meters in length and form dense marine forests.
