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
Monocots have mechanisms to promote or suppress cross-fertilization and self-fertilization (autogamy or geitonogamy). The pollination syndromes of monocots can be quite distinct; they include having flower parts in multiples of three, adaptations to pollination by water (hydrogamy), and pollination by sexual deception in orchids .
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. Their vascular bundles are scattered.
Lilioid monocots (lilioids, liliid monocots, petaloid monocots, petaloid lilioid monocots) is an informal name used for a grade (grouping of taxa with common characteristics) of five monocot orders (Petrosaviales, Dioscoreales, Pandanales, Liliales and Asparagales) in which the majority of species have flowers with relatively large, coloured tepals.
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 ...
cross section of a curled leaf of Ammophila (plant) (40x magnified); white buliform cells are visible at the base of the grooves. During drought, the loss of water through vacuoles induces the reduced bulliform cells to allow the leaves of many grass species to close and the two edges of the grass blade fold toward each other. Once enough water ...
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]
