A monocot taxon has been in use for several decades, but with various ranks and under several different names. The APG IV system recognises its monophyly but does not assign it to a taxonomic rank, and instead uses the term "monocots" to refer to the group. Monocotyledons are contrasted with the dicotyledons, which have two

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 .
English: This diagram is showing the differences between monocotyledonous plants and dicotyledonous plants. Monocots have a single cotyledon and long and narrow leaves with parallel veins.
Adventitious root s may develop from node s of prostrate stems of some plant species, or from the hypocotyl rather than from the radicle of a germinating monocotyledon. adventive Introduced accidentally [13] (usually referring to a weed). aerial Of the air; growing or borne above the surface of the ground or water.

Plants which grow out one of these primordia are called monocotyledons, while those that grow out two are dicotyledons. The next stage is called the Torpedo stage and involves the growth of several key structures, including: the radicle (embryotic root), the epicotyl (embryotic stem), and the hypocotyl, (the root/shoot
Over 130 years after his gruesome murders in East London, England, the descendants of his victims are looking to unmask the identity of the serial killer popularly known as Jack the Ripper. The ...
The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants ...
