Most plastids are photosynthetic, thus leading to color production and energy storage or production. There are many types of plastids in plants alone, but all plastids can be separated based on the number of times they have undergone endosymbiotic events. Currently there are three types of plastids; primary, secondary and tertiary.
These are called tertiary plastids. [23] Possible cladogram of chloroplast evolution [29] [31] [32] Circles represent endosymbiotic events. For clarity, dinophyte tertiary endosymbioses and many nonphotosynthetic lineages have been omitted.
Among the many lines of evidence supporting symbiogenesis are that mitochondria and plastids contain their own chromosomes and reproduce by splitting in two, parallel but separate from the sexual reproduction of the rest of the cell; that the chromosomes of some mitochondria and plastids are single circular DNA molecules similar to the circular ...
The diatom-derived tertiary plastid in Durinskia is not as reduced as other plastids where the secondary host components are completely reduced and only the plastid remains. [12] In addition to retaining the nuclear genome and the large nucleus of the diatom, the diatom's mitochondria and mitochondrial genome, cytosolic ribosomes, and ...
Meta-algae are organisms with photosynthetic organelles of secondary or tertiary endosymbiotic origin, and their close non-photosynthetic, plastid-bearing, relatives. Apicomplexans are a secondarily non-photosynthetic group of chromalveoates which retain a reduced plastid organelle.
Most Dinoflagellates have a plastid derived from secondary endosymbiosis of red algae, however dinoflagellates with plastids derived from green algae and tertiary endosymbiosis of diatoms have also been discovered. [27] Similar to other photosynthetic organisms, dinoflagellates contain chlorophylls a and c2 and the carotenoid beta-carotene.
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
