Many monocots are herbaceous and do not have the ability to increase the width of a stem (secondary growth) via the same kind of vascular cambium found in non-monocot woody plants. [35] However, some monocots do have secondary growth; because this does not arise from a single vascular cambium producing xylem inwards and phloem outwards, it is ...
The pith of the sago palm, although highly toxic to animals in its raw form, is an important human food source in Melanesia and Micronesia by virtue of its starch content and its availability. There is a simple process of starch extraction from sago pith that leaches away a sufficient amount of the toxins and thus only the starch component is ...
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 when monocots and dicots are thought to have diverged.
The alismatid monocots are a group of 15 interrelated families of flowering plants, named for their largest order, Alismatales. [a] Like other monocots, they usually have a single embryonic leaf in their seeds, scattered vascular systems, leaves with parallel veins, flowers with parts in threes or multiples of three, and roots that can develop in more than one place along the stems.

Vascular cambia are found in all seed plants except for five angiosperm lineages which have independently lost it; Nymphaeales, Ceratophyllum, Nelumbo, Podostemaceae, and monocots. [1] In dicot and gymnosperm trees, the vascular cambium is the obvious line separating the bark and wood; they also have a cork cambium.
Juncus acutus, the spiny rush, sharp rush or sharp-pointed rush, is a flowering plant in the monocot family Juncaceae.It is native to the Americas, Northern and Southern Africa, Western and Southern Europe and West Asia, and is found in a variety of wet habitats, such as bogs, fens, meadows, and salt marshes, [2] and along the edges of ponds and lakes.
The animal-shaped cookies soon made their way across the Atlantic to America, where they. These festive treats may remind you of a day at the circus as a child, but the story of how they came to ...
[a] They generally have tepals (indistinguishable petals and sepals) similar to those on the true lilies . [ 5 ] [ 6 ] [ 7 ] Like other monocots [ b ] they usually have a single embryonic leaf ( cotyledon ) in their seeds, scattered vascular systems, leaves with parallel veins , flower parts in multiples of three, and roots that can develop in ...
