WebDiatoms Photosynthesis Definition. Diatoms consist of two kinds of pigments that are involved in photoprotection and light-harvesting- chlorophylls and carotenoids. … WebCarotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments. One very visible accessory pigment is fucoxanthin the brown pigment which colors kelps and other brown algae as well as the diatoms.

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.
