Euglenophyta are photosynthetic organisms of kingdom Protista which are unicellular aquatic algae. Most of them live in freshwater and motile. The photosynthetic pigments contained inside the organisms are chlorophylls a and b.
Some species are heterotrophic and can ingest or absorb their food. They reproduce via longitudinal cell division.
Chlorophyll a -> blue-green pigment; it is the most common photosynthetic pigment. It is the specific chlorophyll used in oxygenic photosynthesis by eukaryotes, cyanobacteria, plants and prochlorophytes.
Chlorophyll b -> yellow-green pigment; helps in the photosynthesis by absorbing the light energy. It is the more soluble chlorophyll because of its carbonyl group in its structure.
Member of the Euglenophyta (e.g., Euglena) have the same photosynthetic pigment distribution as members of the Chlorophyta, but their chloroplasts are enclosed by a triple membrane rather than the usual double membrane found in chloroplasts of green algae.
Euglenophyta is actually a type of algae that is mostly found in the seaward side of the earth therefore, they lack photosynthetic pigments but the ones with chloroplast present have pigments called chlorophyll a and b (common in chlorophyta)...Now if you have been to the coral reef side you would have come across this like alot of times... A very good example is the euglena!!!!!!!!!!!!! taataa...
