The scutellum is part of the structure of a barley and rice [1] seed—the modified seed leaf. The scutellum (from the Latin scutella meaning "small shield") can also refer to the equivalence of a thin cotyledon in monocots (especially members of the grass family ).
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.
Posidonia oceanica is a flowering plant which grows in dense meadows or along sandy channels in the waters of the Mediterranean. It is found at depths of 1–35 metres (3.3–114.8 ft), [8] depending on water clarity. Subsurface rhizomes and roots stabilize the plant, while erect rhizomes and leaves reduce silt accumulation.
In nature, this hardy species is found in shallow water, often as an epiphyte on other algae. It features lightly calcified, maroon branches which require adequate flow to be maintained. [220] 6 in (15.2 cm) [221] Filamentous red alga: Kapraunia schneideri: This is a seasonal species and is naturally found attached to hard surfaces in winter. [13]
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Scutellum may refer to: Scutellum (insect anatomy), a term used in the anatomy of arthropods; Scutellum (botany), a term used in the morphology of grasses;
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [28] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.
A number of studies from around the world have found that there is a wide range in the concentrations of C, N, and P in seagrasses depending on their species and environmental factors. For instance, plants collected from high-nutrient environments had lower C:N and C:P ratios than plants collected from low-nutrient environments.
