This grass favours high-salinity waters with low turbidity, such as calm lagoons. It cannot grow in fresh water but some growth is possible at a salinity of 10 parts per thousand. The plant's preferred salinity range is 25 to 38.5 parts per thousand with a temperature range of 20 to 30 °C (68 to 86 °F).
Monocots are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf or cotyledon. [12] Terrestrial plants evolved perhaps as early as 450 million years ago from a group of green algae. [13] Seagrasses then evolved from terrestrial plants which migrated back into the ocean.
Seagrasses are flowering plants (angiosperms) which grow in marine environments. They evolved from terrestrial plants which migrated back into the ocean about 75 to 100 million years ago. [ 1 ] [ 2 ] In the present day they occupy the sea bottom in shallow and sheltered coastal waters anchored in sand or mud bottoms.
Marine plants can be found in intertidal zones and shallow waters, such as seagrasses like eelgrass and turtle grass, Thalassia. These plants have adapted to the high salinity of the ocean environment. Light is only able to penetrate the top 200 metres (660 ft) so this is the only part of the sea where plants can grow. [77]
Holodiscus discolor is a fast-growing deciduous shrub usually from to 1.2–1.5 metres (4–5 feet) in width, and up to 2.1 m (7 ft) tall. Its alternate leaves are small, 5–9 centimetres (2– 3 + 1 ⁄ 2 inches) long and 4–7 cm (1 + 1 ⁄ 2 –3 in) broad, lobed, juicy green when new. [6]
Spartina is a genus of plants in the grass family, frequently found in coastal salt marshes. [3] Species in this genus are commonly known as cordgrass or cord-grass, [4] and are native to the coasts of the Atlantic Ocean in western and southern Europe, north-western and southern Africa, the Americas and the islands of the southern Atlantic Ocean; one or two species also occur on the western ...
Cymodocea nodosa is a species of seagrass in the family Cymodoceaceae [3] and is sometimes known as little Neptune grass. [4] As a seagrass, it is restricted to growing underwater and is found in shallow parts of the Mediterranean Sea and certain adjoining areas of the Atlantic Ocean .
Posidonia oceanica, commonly known as Neptune grass or Mediterranean tapeweed, is a seagrass species that is endemic to the Mediterranean Sea. [2] It forms large underwater meadows that are an important part of the ecosystem.
