Nutrition of Algae

Abstract

The photosynthetic #-flagellates, probably outnumbering all other algae save perhaps the zooxanthellae packing phofic-zone corals, embody virtually every conceivable mishmash of "plant" and "animal" characters. juxtapositions rine, chloroplast-bearlng Further of plant and animal are embodied in minute, flagellated, ma- amebae (164); such amebae, some without flagella were described from bogs long algo by Pascher and are figured in Fott’s text- book (49) and in Bourrelly’s (25) treatise on chrysomonads. Such amebae probably are not rare but the tendency has been to interpret chloroplasts as food vacuoles. We shall therefore emphasize findings that relate algal physi- ology to comparative biochemistry. Synchronous and rhythmic growth has been reviewed (165, 177) and will not be discussed here. TECHNICAL
