Very little of us know what algae is and how it has ginormous impact it has on our planet. + + + + + + + + Previous Series: Tattoos: The Ancient Art And Future Technology: https://www.youtube.com/playlist?list=PLwwOk5fvpuuKJD9TjtwtSiN9qmB16rlAp + + + + + + + + Algae May Hold Key to Origin of the Sexes: http://www.livescience.com/46697-algae-sex-gene-identified.html' "A tiny, unassuming little alga may hold the secret to how the sexes evolved.A single gene that determines male or female sex in multicellular algae evolved from a more primitive version found in a single-celled ancestor that doesn't have sexes, according to a new study." THE ORIGIN OF LAND PLANTS: http://www.amjbot.org/content/91/10/1535.full -44 "Standard textbooks on botany and phycology acknowledge a world view in which the green algae as a whole are no longer monophyletic to the exclusion of land plants (embryophytes; Raven et al., 1999?; Graham and Wilcox, 2000a?; Graham et al., 2002?; Judd et al., 2002?)." All Land Plants Evolved From Single Type of Algae, Scientists Say: http://news.nationalgeographic.com/news/2001/06/0604_wirealgae.html "The first tentative moves that got life out of the water and onto the land eons ago were apparently made by slimy green algae, scientists say, and coming ashore wasn't easy." Timeline of Photosynthesis on Earth: http://www.scientificamerican.com/article/timeline-of-photosynthesis-on-earth/ "Photosynthesis evolved early in Earth's history. The rapidity of its emergence suggests it was no fluke and could arise on other worlds, too. As organisms released gases that changed the very lighting conditions on which they depended, they had to evolve new colors." Polyphyletic: http://www.dictionary.com/browse/polyphyletic "adjective 1.developed from more than one ancestral type, as a group of animals." Blue-green algae: https://www.britannica.com/science/blue-green-algae "Blue-green algae, also called cyanobacteria, any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches, and were at one" Turbidity: http://www.lenntech.com/turbidity.htm "Turbidity is a measure of the degree to which the water loses its transparency due to the presence of suspended particulates. The more total suspended solids in the water, the murkier it seems and the higher the turbidity." Eukaryote: https://www.sciencedaily.com/terms/eukaryote.htm "A eukaryote is an organism with a complex cell or cells, in which the genetic material is organized into a membrane-bound nucleus or nuclei." What Is Photosynthesis?: http://www.livescience.com/51720-photosynthesis.html "Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy." Overfishing linked to algal blooms: http://www.nature.com/news/2009/091201/full/news.2009.1116.html "Nitrogenous fertilizers and detergents have long been known to cause algal blooms that block sunlight and strangle ecosystems, but a study now reveals that overfishing of large predatory fish is also playing a key part." What Are Algae?: http://www.livescience.com/54979-what-are-algae.html "Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes." The diving pool at the Olympics is closed after turning green. Here's what happened.: http://www.vox.com/2016/8/9/12417804/rio-olympics-2016-pool-green "On Tuesday, something happened to the diving pool at the Rio Olympics. It turned green. Not just a little green. No. This was full-on lime Jell-O green, close to the color swatch movie set designers turn to when they want to make something look radioactive." + + + + + + + + DNews Plus is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love.
