WebDec 4, 2024 · Diatoms, like all autotrophs, are photosynthetic and use the sun’s energy to absorb carbon and store carbohydrates. It is an evolutionary system that uses the energy obtained from carbohydrates oxidation (i.e. respiration) to carry out a variety of life functions, including the acquisition and accumulation of other life-sustaining elements. 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.
