The green algae and the charophytes represent the most widely studied groups of algae in respect to their ploidy levels. In some genera increased size accompanies ploidy level changes as well as certain morphological modifications, but in other genera no evident obvious changes can be discerned.

Thraustochytrids, a heterotrophic fungus-like clade of Stramenopiles, are becoming an increasingly important source of polyunsaturated fatty acids (PUFAs) for biotechnological industries. PUFA rich oils from these organisms are subsequently referred to in some literature and marketing sources as being derived from 'algae', in spite of their non ...

Algae Crops: Coproduction of Algae Biofuels
2014The chapter discusses potential uses of algae, and the benefits of coproducing algae biofuels and value-added products such as wastewater treatment and fish. Because of the discussion and the data surrounding algae, and the large technical and economic barriers faced by producers of algae biofuels, we predict that the use of algae to produce energy ...

The brown algae comprise the class Phaeophyceae, golden-brown algae that range from small filamentous forms to large, complex seaweeds. Of the estimated 1,836 species in approximately 285 genera, fewer than 1% are found in freshwater habitats. Because so few freshwater brown algae exist worldwide and new discoveries are continuing, this chapter ...

The Haptophyta is a unique division of algae, members of which possess a haptonema—a flagellum-like structure used for phagotrophic nutrition and/or for attachment to external surfaces. An extracellular layer of endogenously produced organic scales with species-specific shapes and ornamentations is also characteristic of most freshwater genera.
