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 ...
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 ...
Basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group. [11] A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots. [12] The Pentapetalae can be then divided into three clades: [citation needed]
Monocotyledon reproduction. A solitary bee pollinating an Allium monocot flower. The monocots (or monocotyledons) are one of the two major groups of flowering plants (or Angiosperms), the other being the dicots (or dicotyledons). In order to reproduce they utilize various strategies such as employing forms of asexual reproduction, restricting ...
Cotyledon from a Judas-tree (Cercis siliquastrum, a dicot) seedling Comparison of a monocot and dicot sprouting. The visible part of the monocot plant (left) is actually the first true leaf produced from the meristem; the cotyledon itself remains within the seed Schematic of epigeal vs hypogeal germination Peanut seeds split in half, showing the embryos with cotyledons and primordial root Two ...
There are 27 families of flowering plants whose earliest ancestors diverged from what became the two most prominent groups of flowering plants, the eudicots and monocots. They are quite diverse, with woody and non-woody plants, evergreen and deciduous shrubs and trees, and plants that grow in soil, in water and on other plants.
The alismatid monocots are a group of 15 interrelated families of flowering plants, named for their largest order, Alismatales. [a] Like other monocots, they usually have a single embryonic leaf in their seeds, scattered vascular systems, leaves with parallel veins, flowers with parts in threes or multiples of three, and roots that can develop in more than one place along the stems.

The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [a] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or ...
