WebJul 14, 2024 · As photosynthetic pigments, chlorophyll a plays a role in light harvesting, energy transfer, and light energy conversion, while chlorophyll c in diatom is involved in light harvesting in spite of much smaller amounts than chlorophyll a [24,25]. Meanwhile, to further characterize the photosynthetic activity of mixotrophic and photoautotrophic ...

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. They have a cell wall with … See more Diatoms generally reproduce asexually by mitosis. The two frustules separate, each with a nucleus and cytoplasm. Each daughter constructs … See more Here are a select few of the many interactions involving diatoms: 1. global ecology—It is estimated that diatoms account for over 40% of the ocean’s production of oxygen and reduced carbon. Therefore the group … See more Diatoms are photosynthetic and are typical autotrophs, using the sun’s energy to reduce carbon and accumulate carbohydrates, and using the energy obtained from the … See more WebPhylogenetic and gene expression analysis of cyanobacteria and diatoms in the twilight waters of the temperate northeast Pacific Ocean Microb Ecol. 2011 Nov;62(4) :765-75. doi ... -transcription PCR approaches had been employed to detect expression of the genes involved in protein synthesis and photosynthesis of photoautotrophic organisms, and ...
