Monocotyledon
Monocotyledons are a class of flowering plants (angiosperms), whose embryo (seed) store only one cotyledon. The APG II system recognises a clade called "monocots" but does not assign it to a taxonomic rank.

You can recognize a monocot by its leaves: they have long parallel veins running down the leaf. In contrast, dicot plant leaves have a complex netted vein pattern on their leaves.
Monocots usually have a fibrous root system.
