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. [1] Aristida – 288 C 4 ...
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]

The mesocarp (from Greek: meso-, "middle" + -carp, "fruit") is the fleshy middle layer of the pericarp of a fruit; it is found between the epicarp and the endocarp. [8] It is usually the part of the fruit that is eaten. For example, the mesocarp makes up most of the edible part of a peach, and a considerable part of a tomato.
However, for many years after Brown's discovery, the primary division of the seed plants was seen as between monocots and dicots, with gymnosperms as a small subset of the dicots. [4] In 1851, Hofmeister discovered the changes occurring in the embryo-sac of flowering plants, and determined the correct relationships of these to the Cryptogamia.
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.
