Monocotyledons do not necessarily have endosperm. The existence of endosperm of seeds can be divided into four types according to the presence or absence of endosperm: Dicotyledonous seeds have endosperm: Although these seeds belong to dicotyledonous plants, they have endosperm, such as castor, lotus, buckwheat, carrot, amaranth, Dianthus, persimmon, etc. Dicotyledonous non-endosperm seeds: These seeds are dicotyledonous plants but do not have endosperm, such as cotton, soybeans, peanuts, sunflower, etc.
I think there are significant differences between monocotyledonous and dicotyledonous plants in seed endosperm, leaf structure and number of petals. The endosperm of monocotyledonous seeds is the aleurone layer, and the endosperm of dicotyledonous seeds contains starch and protein.
Monocotyledons refer to plants with endosperm among seed plants, such as onions, garlic, lily, etc. The seeds of these plants have no endosperm, but embryos are present and only one cotyledon. Unlike dicotyledonous plants, monocotyledons have only one cotyledon, a curved embryo, and a long tubular cotyledon. In addition, monocotyledons have only one leaf and do not form veins, flowers vary in shapes and sizes, and pollen grains are small.
