Why is yam classified under monocotyledon?

Yam is classified as a monocotyledon because it possesses characteristics typical of monocots, such as having a single seed leaf (cotyledon) in its embryonic stage. Additionally, yams exhibit parallel leaf venation, flower parts typically in multiples of three, and a fibrous root system, which are all common traits of monocotyledonous plants. These features align with the broader classification of monocots within the angiOSperms.
