WebApr 10, 2024 · The phycobiliproteins that give Mesodinium cells their color are accessory pigments. This means that they harvest additional wavelengths of light that are not already captured by chlorophyll for photosynthesis. But when overall light levels are high, a chloroplast can harvest all the light it needs with chlorophyll alone.
WebCryptophytes are an ecologically important group of largely photosynthetic unicellular eukaryotes. This lineage is of great interest to evolutionary biologists because their plastids are of red algal secondary endosymbiotic origin and the host cell retains four different genomes (host nuclear, mitochondrial, plastid, and red algal nucleomorph). dave and busters grand prairie txWebCiliophora.
