Scientists developed the ATS, which consists of shallow, 100-foot raceways of nylon netting where algae colonies can form, and studied its efficacy for three years. They found that algae can readily be used to reduce the nutrient runoff from agricultural fields and increase the quality of water flowing into rivers, streams, and oceans.
Green, red and brown algae all have multicellular macroscopic forms that make up the familiar seaweeds. Green algae , an informal group, contains about 8,000 recognised species. [ 145 ] Many species live most of their lives as single cells or are filamentous, while others form colonies made up from long chains of cells, or are highly ...

Marine prokaryotes have been the dominant life form for most of Earth's history, perhaps because water protected them from ionizing radiation [8] The Earth is about 4.54 billion years old. [ 9 ] [ 10 ] [ 11 ] The earliest undisputed evidence of life on Earth dates from at least 3.5 billion years ago, [ 12 ] [ 13 ] during the Eoarchean Era after ...
All forms of life in the sea have the potential to become food for another life form. In the ocean, a food chain typically starts with energy from the sun powering phytoplankton, and follows a course such as: phytoplankton → herbivorous zooplankton → carnivorous zooplankton → filter feeder → predatory vertebrate
Chlorophyta (green algae), mostly unicellular algae found in fresh water. [44] The chlorophyta are of particular importance because they are believed to be most closely related to the evolution of land plants. [45] Diatoms, unicellular algae that have siliceous cell walls. [46] They are the most abundant form of algae in the ocean, although ...
Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a] Staghorn algae of the genus Compsopogon may exist on aquarium substrates and can be epiphytic on slow-growing plants. [2] It can form branched, whitish-green strands up to six inches ...
The green algae include unicellular and colonial flagellates, usually but not always with two flagella per cell, as well as various colonial, coccoid, and filamentous forms. In the Charales , which are the algae most closely related to higher plants, cells differentiate into several distinct tissues within the organism.
