Dicot & Monocot Seeds also known as monocots, are one of the major groups into which flowering plants (or angiosperms) are divided. Traditionally, the rest of the flowering plants were classed as dicotyledons, or dicots. Monocot seedlings typically have one cotyledon (seed-leaf), in contrast to the two cotyledons typical of dicots. Modern research using molecular phylogenetic methods has shown that the monocots form a natural group – a clade – since they comprise all the descendants of a common ancestor. Dicots, by contrast, do not form a natural group.
