Flower of Liriodendron tulipifera, a Mesangiosperm. Mesangiospermae is a clade that contains the majority of flowering plants (angiosperms). Mesangiosperms are therefore known as the core angiosperms, in contrast to the three orders of earlier-diverging species known as the basal angiosperms: Nymphaeales (including water lilies), Austrobaileyales (including star anise), and Amborellales.
The monocots or monocotyledons have, as the name implies, a single (mono-) cotyledon, or embryonic leaf, in their seeds.Historically, this feature was used to contrast the monocots with the dicotyledons or dicots which typically have two cotyledons; however, modern research has shown that the dicots are not a natural group, and the term can only be used to indicate all angiosperms that are not ...
The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this ...
Angiosperms are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. [8] They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants.
Flower Pennisetum pedicellatum growing in the wild. Desho is a herbaceous perennial grass which has a massive root system that anchors to the soil. [5] It has a high biomass producing capacity and grows upright with the potential of reaching 90 cm to 120 cm in height depending on soil fertility.
angiosperm A flowering plant; a plant with developing seeds enclosed in an ovary. anisomery The condition of having a floral whorl with a different (usually smaller) number of parts from the other floral whorls. anisotomic Branching, with branches having unequal diameters, such as a trunk and its branch. Contrast isotomic. annual
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
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.
