Monocotyledons or monocots are one of two major groups of flowering plants (angiosperms) that are traditionally recognized, the other being dicotyledons or dicots. Monocot seedlings typically have one cotyledon (seed-leaf), in contrast to the two cotyledons typical of dicots. Monocots have been recognized at various taxonomic ranks, and under various names (see below). The APG II system recognises a clade called "monocots" but does not assign it to a taxonomic rank.
Monocots comprise the majority of biomass produced in agriculture. There are between 50,000 and 60,000 species within this group; according to IUCN there are 59,300 species.
The name monocotyledons is derived from the traditional botanical name Monocotyledones, which derives from the fact that most members of this group have one cotyledon, or embryonic leaf, in their seeds. By contrast, the traditional Dicotyledons typically have two cotyledons. From a diagnostic point of view the number of cotyledons is neither a particularly handy (as they are only present for a very short period in a plant's life), nor totally reliable character.
Nevertheless, monocots are a distinctive group.[2] One of the most noticeable traits is that a monocot's flower is trimerous, with the flower parts in threes or in multiples of three. That is to say, a monocotyledon's flower typically has three, six, or nine petals. Many monocots also have leaves with parallel veins.
The traditionally listed differences between monocotyledons and dicotyledons are as follows. This is a broad sketch only, not invariably applicable, as there are a number of exceptions. The differences indicated are more true for monocots versus eudicots.[2]
Feature | In monocots | In dicots |
---|---|---|
Number of parts of each flower | in threes (flowers are trimerous) | in fours or fives (tetramerous or pentamerous) |
Number of furrows or pores in pollen | one | three |
Number of cotyledons (leaves in the seed) | one | two |
Arrangement of vascular bundles in the stem | scattered | in concentric circles |
Roots | are adventitious | develop from the radicle |
Arrangement of major leaf veins | parallel | reticulate |
A number of these differences are not unique to the monocots.
