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 ).
The scutellum covers the abdomen and the tarsus is bipartite. [2] [3] Distribution. This species can be found in most of southern Europe and it is widespread from ...
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. The leaves are ribbon-like, appearing in tufts of 6 or 7, and up to 1.5 metres (4.9 ft) long.
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.
The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. The scutellum is a tissue within the seed that is specialized to absorb stored food from the adjacent endosperm. The coleoptile is a protective cap that covers the plumule (precursor to the stem and leaves of the plant).
Seagrass cell walls contain the same polysaccharides found in angiosperm land plants, such as cellulose [101] However, the cell walls of some seagrasses are characterised by sulfated polysaccharides, [102] [103] which is a common attribute of macroalgae from the groups of red, brown and also green algae.
"Seaweed" lacks a formal definition, but seaweed generally lives in the ocean and is visible to the naked eye. The term refers to both flowering plants submerged in the ocean, like eelgrass, as well as larger marine algae. Generally, it is one of several groups of multicellular algae; red, green and brown.

Venus' flower basket (Euplectella aspergillum) is a species of marine glass sponge found in the deep waters of the Pacific Ocean, usually at depths below 500 m (1,600 ft). Like other sponges, they feed by filtering sea water to capture plankton and marine snow . [ 1 ]
