Algae lack the various structures that characterize plants (which evolved from freshwater green algae), such as the phyllids (leaf-like structures) and rhizoids of bryophytes (non-vascular plants), and the roots, leaves and other xylemic/phloemic organs found in tracheophytes (vascular plants).
Algae (UK: / ˈ æ l ɡ iː / AL-ghee, US: / ˈ æ l dʒ iː / AL-jee; [3] sg.: alga / ˈ æ l ɡ ə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Plastic is a breeding ground for algae, so the sea birds mistakenly eat the bag rather than the fish that typically ingests algae. (National Geographic) [ 22 ] Plastic bags do not do well in the environment, but several government studies have found them to be an environmentally friendly carryout bag option.
Zygnema is a genus of freshwater filamentous thalloid alga comprising about 100 species. [4] A terrestrial species, Z. terrestre, is known from India.Zygnema grows as a free-floating mass of filaments, although young plants may be found anchored to streambeds with a holdfast.
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
The "Algaeus" was the moniker for a modified Toyata Prius that ran on algal fuel. [1]The vehicle was produced by Sapphire Energy, maker of an algae-based replacement for gasoline and jet fuel, and was unveiled in front of San Francisco's City Hall on September 8th, 2008.
Bangia grows in freshwater or in marine habitats, usually forming dense clumps or mats, and occur throughout the intertidal area and subtidally to the maximum depth at which benthic algae occur. The plants are usually attached to a solid substratum (rock or shell), but can also occur as epiphytes attached to other algae.
