There are seven types of algae based on the different types of pigmentation and the food reserves. The red pigment called phycobilin helps in harvesting light at a greater depth. One thing is certain, however: algae are present in any body of water, and while there are ways to control them, it’s impossible to completely avoid them. In the ocean, they occur as nanoplanktons and normally have a rapid rate of productivity compared to the diatoms. They belong to Rhodophyta, and they contain chlorophyll ‘a’, ‘d’, carotenoids, xanthophylls, and phycobilins. Their main food reserve is starch. They appear a lighter green since their chloroplasts lack a certain pigmentation. This type of algae contain chloroplasts and can synthesize their own food through the process of photosynthesis.

Most of them are freshwater algae, while a few species are found in the marine water. The differences in the pigments play a major role in determining the habitat distribution of the particular algal species. BGA are considered to be an intermediate between bacteria and plants. This algae isn't particularly common, but has the ability to grow rapidly from fragments. Several types of red algae are used in food additives, and some are regular parts of Asian cuisine. The term \"algae\" covers many different organisms capable of producing oxygen through photosynthesis (the process of harvesting light energy from the sun to generate carbohydrates). They contain flagella which enables them to feed on organic matter in their surroundings. These unicellular organisms are the rarest and least prolific species of algae with only 450 to 650 species. Rhodophyta contains a cell wall that is made up of cellulose and other types of carbohydrates. Vegetative reproduction occurs through fragmentation, asexual occurs through formation of spores and binary fission, whereas sexual reproduction takes place by fusion…, Algae are a group of autotrophic and eukaryotic organisms. They occur in a wide range of sizes: some are tiny single cells, while others such as giant kelp can be more than 45 metres long.

The group is fairly diverse in form, and its taxonomy is contentious. Also called Rhodophyta, it is a distinctive species found in marine as well as freshwater ecosystems. Based on the occurrence of pigments and food reserves, algae are classified into different types, namely blue green algae (BGA), green algae, red algae, and brown algae. Some researchers say algae could be 10 or even 100 times more productive than traditional bioenergy crops. These organisms can occur as either single cell organisms or multicellular species for the large ones. 8. It could be either blue-black, yellow, or even green. Some examples of this type are Ulva, Codium, and Caulerpa.
