Turtle grass can also sexually reproduce through the production of underwater flowers and hydrophily. Turtle grass is dioecious, which means that there are separate male and female plants, each which produce an imperfect flower containing only one sex. Sexual reproduction takes place from April to July depending on location, though flowering ...
For instance, plants collected from high-nutrient environments had lower C:N and C:P ratios than plants collected from low-nutrient environments. Seagrass stoichiometry does not follow the Redfield ratio commonly used as an indicator of nutrient availability for phytoplankton growth. In fact, a number of studies from around the world have found ...
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.
Syringodium filiforme, commonly known as manatee grass, is a species of marine seagrass. It forms meadows in shallow sandy or muddy locations in the Caribbean Sea and the Gulf of Mexico, and is also found in the Bahamas and Bermuda. [1] [2] It occurs to a depth of about 20 m (66 ft), and even deeper where water is very clear. [1]
The biota of an aquatic ecosystem contribute to its self-purification, most notably microorganisms, phytoplankton, higher plants, invertebrates, fish, bacteria, protists, aquatic fungi, and more. These organisms are actively involved in multiple self-purification processes, including organic matter destruction and water filtration.
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
Ocean currents are also generated by the gravitational pull of the sun and moon , and seismic activity . [17] The rotation of the Earth affects the direction ocean currents take, and explains which way the large circular ocean gyres rotate in the image above left. Suppose a current at the equator is heading north.
Ruppia maritima is an aquatic plant species commonly known as beaked tasselweed, beaked ditchgrass, [citation needed] ditch grass, tassel pondweed and widgeon grass. [2] Despite its scientific name , it is not a marine plant ; is perhaps best described as a salt-tolerant freshwater species. [ 3 ]
