The monocots 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 paraphyletic. From a diagnostic point of view the number ...
Grass on golf courses is kept in three distinct conditions: that of the rough, the fairway, and the putting green. Grass on the fairway is mown short and even, allowing the player to strike the ball cleanly. Playing from the rough is a disadvantage because the long grass may affect the flight of the ball.
Monocots – mainly grasses and sedges – account for around 80% of C 4 species, but they are also found in the eudicots. [1] Moreover, almost all C 4 plants are herbaceus, with the notable exception of some woody species from the Euphorbia genus, such as the tree Euphorbia olowaluana. [6]
Aside from cotyledon number, other broad differences have been noted between monocots and dicots, although these have proven to be differences primarily between monocots and eudicots. Many early-diverging dicot groups have monocot characteristics such as scattered vascular bundles, trimerous flowers, and non-tricolpate pollen. [5]

In agriculture the majority of the biomass produced comes from monocots. [4] The true grasses, family Poaceae (Gramineae), are the most economically important family in this group. These include all the true grains (rice, wheat, maize, etc.), the pasture grasses, sugar cane, and the bamboos. True grasses have evolved to become highly ...
Dactylis glomerata is a species of flowering plant in the grass family Poaceae, known as cock's-foot, [2] also colloquially as orchard grass, or cat grass (due to its popularity for use with domestic cats). It is a cool-season perennial C 3 tufted grass native throughout most of Europe, temperate Asia, and northern Africa. [3] [2] [4] [5] [6]
Reproducing through seeds is the most widespread method of reproduction in both monocots and dicots. However, internal seed structure is vastly different between these groups. The cotyledon is the embryonic leaf within a seed; monocots have one whereas dicots have two. The evolution of having one or two cotyledons may have arisen 200-150 Mya ...
