Allium crenulatum (Asparagales), an onion, with typical monocot perianth and parallel leaf venation Onion slice: the cross-sectional view shows the veins that run in parallel along the length of the bulb and stem. The monocots have, as the name implies, a single (mono-) cotyledon, or embryonic leaf, in their seeds.
basal: attached close to the base (of a plant or an evolutionary tree diagram) climber: a vine that leans on, twines around or clings to other plants for vertical support; glandular hair: a hair tipped with a secretory structure; herbaceous: not woody; usually green and soft in texture; perennial: not an annual or biennial
Two-barrel downdraft Holley 2280 carburetor Cross-sectional schematic. A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4]
Although carburetor technology in automobiles reached a very high degree of sophistication and precision, from the mid-1980s it lost out on cost and flexibility to fuel injection. Simple forms of carburetor remain in widespread use in small engines such as lawn mowers and more sophisticated forms are still used in small motorcycles.
Monocot flowers occur with parts having multiples of three; usually there are three stamen, three petals and three sepals (six tepals), and usually just one stigma. [18] However stamens in twos can be found in Cypripedioideae while single fertile stamens can be found in Philydraceae , Zingiberaceae , and as gynostemium in Orchidacaea .
Of the monocot clades containing C 4 plants, the grass species use the C 4 photosynthetic pathway most. 46% of grasses are C 4 and together account for 61% of C 4 species. C 4 has arisen independently in the grass family some twenty or more times, in various subfamilies, tribes, and genera, [ 29 ] including the Andropogoneae tribe which ...

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.
