Diatoms photosynthetic
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. WebJun 28, 2024 · Photosynthesis in Diatoms.

Vegetative cells are, so far, known to be diploid. Mitosis occurs in the diploid phase. Haploid cells, however, have occasionally occurred in culture. Most diatom cells have a large central vacuole, or pair of vacuoles. During the stationary-phase of the cell cycle ...
