WebChlorophyll a, chlorophyll c, and fucoxanthin are the major light-harvesting pigments for photosynthesis. Chloroplast DNA is usually concentrated within a ring-shaped nucleoid at the periphery of the plastid (but there are exceptions in some diatoms!) β-1,3-linked glucan is the primary polysaccharide and serves as storage. WebDiatoms are microscopic, unicellular, autotrophic, and ubiquitous. They are the main organisms in the marine ecosystem which have photosynthetic as well as photoprotective and antioxidant properties. All of these properties facilitate the effective production of biomass and oxygen. Chlorophyll a/c and fucoxanthin (Fx) are the core light ...

The decrease in rETR PSII suggests that P. delicatissima may contain some PCn, which functioning might have been limited by Cu. A lack of PCn electron carrier might have …
The diatoms represent a distinct group but the placement of the diatom group is problematic both in terms of level (phylum or class) and in terms of phylogeny (i.e. who are they grouped with).They may be placed in the ‘miscellaneous’ kingdom, the Protist Kingdom, which is practical but not phylogenetically … See more Diatoms are unicellular, and like most (but not all!) unicellular organisms, they are small, generally 20-100 um in size, and only visible to the naked eye as dust.
