Webb9 okt. 2024 · Photosynthesis and Chloroplasts. You will read that only plants, algae, and some bacteria are photosynthetic. There is an exception to this, however. One species of sea slug has found a way to steal chloroplasts, store them in glands lining its digestive tract, and live on the sugar that is produced (Milius, 2010). Webb29 jan. 2015 · The photosynthesis process produces carbohydrates and lipids, which nourish the slug. How the slug manages to maintain these photosynthesizing organelles for so long has been the topic of intensive study and a good deal of controversy.

Webb26 nov. 2024 · One of the main mysteries regarding photosynthetic sea slugs is how the slug plastids handle photoinhibition, the constant light-induced damage to Photosystem II of photosynthesis. Recovery from photoinhibition involves proteins encoded by both the nuclear and plastid genomes, and slugs with plastids isolated from the algal nucleus are … Webb22 juli 2024 · Solar-Powered Sea Slugs Becoming Too Rare to Study Elysia cholorotica, a sea slug found off the U.S. East Coast, can steal photosynthetic plastids from algae and survive by basking in the sun.... megalodon shark toy

Webb2 maj 2013 · The basis of long-term maintenance of photosynthesis in this sea slug was thought to be explained by extensive horizontal gene transfer (HGT) from the nucleus of the alga to the animal nucleus,... WebbThese data resolve a long-standing issue and suggest that HGT is not the primary reason underlying long-term maintenance of photosynthesis in E. chlorotica. Therefore, sea slug photosynthesis is sustained in as yet unexplained ways that do not appear to endanger the animal germ line through the introduction of dozens of foreign genes. WebbThe slug retains the chloroplasts within in its cells in a functioning state; they apparently are physiologically important to the host. In addition, the slugs likely rely on photosynthesis of the chloroplasts as an energy source, especially when other food sources are not available.
