The oils from some algae have high levels of unsaturated fatty acids. Algae span both terrestrial and marine environments, growing almost anywhere there is water and sunlight. Chlorarachniophytes, which belong to the phylum Cercozoa, contain a small nucleomorph, which is a relict of the algae's nucleus. The algae contain chloroplasts that are similar in structure to cyanobacteria. plural noun Word forms: singular alga (ˈælɡə) unicellular or multicellular organisms formerly classified as plants, occurring in fresh or salt water or moist ground, that have chlorophyll and other pigments but lack true stems, roots, and leaves. { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_rightslot_flex' }}, Maerl is commonly used as a soil conditioner. Coral reefs are accumulated from the calcareous exoskeletons of marine invertebrates of the order Scleractinia (stony corals).

[48] The loss of Symbiodinium from the host is known as coral bleaching, a condition which leads to the deterioration of a reef. Linnaeus, in Species Plantarum (1753),[23] the starting point for modern botanical nomenclature, recognized 14 genera of algae, of which only four are currently considered among algae. [40] The most complex forms are found among the charophyte algae (see Charales and Charophyta), in a lineage that eventually led to the higher land plants.
