The monocots or monocotyledons 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 not a natural group, and the term can only be used to indicate all angiosperms that are not ...
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 ...
D. Plumule: the plumule is the shoot of the seed where the leaves will first appear. E. Radicle: the radicle is the root of the seed. In the monocot seed there are also five major parts. A. Seed coat: the seed coat protects the seed. B. Cotyledon: the cotyledon is the leaf of the seed; there is only one cotyledon in monocot seeds. D.
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. Their petals or flower parts are in multiples of three. Dicots have two cotyledons and broad leaves with network of veins.
A solitary bee pollinating an Allium monocot flower. The monocots (or monocotyledons) are one of the two major groups of flowering plants (or Angiosperms), the other being the dicots (or dicotyledons). In order to reproduce they utilize various strategies such as employing forms of asexual reproduction, restricting which individuals they are ...
Diagram of fine scale leaf internal anatomy. The epidermal tissue includes several differentiated cell types: epidermal cells, guard cells, subsidiary cells, and epidermal hairs . The epidermal cells are the most numerous, largest, and least specialized. These are typically more elongated in the leaves of monocots than in those of dicots.
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system.

Diagram of the internal structure of a leaf. Palisade cell, or palisade mesophyll cell are plant cells located inside the mesophyll of most green leaves.They are vertically elongated and are stacked side by side, in contrast to the irregular and loosely arranged spongy mesophyll cells beneath them.
