Caryopsis: a one-seeded, dry fruit o Embryo - leaves Cotyledon – seed leaf Monocot has one (aka scutellum) Scutellum – one seed leaf It remains where the seed is placed Coleoptile: protective leaf; it emerges from soil (Coleo means protect) o Embryo – stem Epicotyl – portion of stem above the cotyledon No stem tissue below the cotyledonary node (node marks division between stem and root)

03-130, Plant Science Seed Anatomy Lab page 3 o Embryo – root Radicle: embryonic root, Forms the primary root upon germination Coleorhiza: sheath protecting tip of primary root Rhiza –root o Stored Food Endosperm serves as nutrient source for developing seedling Aleurone: outermost layer of the endosperm
