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.
The grass family includes most of the known C 4 species – around 5000. They are only found in subfamilies of the PACMAD clade. Major C 4 crops such as maize, sugarcane, sorghum and pearl millet belong in this family. The only known species with C 3, C 4 and intermediate variants, Alloteropsis semialata, is a grass.

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]
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 ...
[5] [6] [7] Like other monocots [b] they usually have a single embryonic leaf in their seeds, scattered vascular systems, leaves with parallel veins, flower parts in multiples of three, and roots that can develop in more than one place along the stems. [11]
The Cyperaceae (/ ˌ s aɪ p ə ˈ r eɪ s i. iː,-ˌ aɪ /) are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges.The family is large; botanists have described some 5,500 known species in about 90 genera [3] [4] – the largest being the "true sedges" (genus Carex), [5] [6] with over 2,000 species.
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]
