<P> A cotyledon ( / kɒtɪˈliːdən / ; `` seed leaf '' from Latin cotyledon , from Greek : κοτυληδών kotylēdōn , gen. : κοτυληδόνος kotylēdonos , from κοτύλη kotýlē `` cup , bowl '' ) is a significant part of the embryo within the seed of a plant , and is defined by the Oxford English Dictionary as `` The primary leaf in the embryo of the higher plants ( Phanerogams ) ; the seed - leaf . '' Upon germination , the cotyledon may become the embryonic first leaves of a seedling . The number of cotyledons present is one characteristic used by botanists to classify the flowering plants ( angiosperms ) . Species with one cotyledon are called monocotyledonous ( `` monocots '' ) . Plants with two embryonic leaves are termed dicotyledonous ( `` dicots '' ) and placed in the class Magnoliopsida . </P>
