| Cotyledons absent (= embryo macropodial) | A massive embryo that shows no obvious cotyledons. |  |
| Embryo | The young sporophytic plant found inside of the seed. |  |
| Embryo | A young seed plant found within the seed, a dicotyledon embryo consists of the hypocotyle, cotyledons (usually two), and the epicotyl. |  |
| Embryo air chamber | Referring to an embryo with a chamber inside of the seed caused by bowed cotyledons. |  |
| Embryo macropodial (= cotyledons absent) | Massive embryo that shows no obvious cotyledons. Cotyledons absent is the preferred term. | |
| Embryo sac | The female gametophyte of angiosperms (flowering plants). Same as megagametophyte. |  |
| Eugenioid embryo | A type of embryo found in the Myrtaceae in which the cotyledons are thick, separate, and plano-convex (like those of a bean) and the hypocotyl is a short protrusion, or the cotyledons are fused partially or completely into a single mass and the hypocotyl is not distinguishable. Compare with myrcioid embryo and myrtoid embryo. |  |
| Macropodial embryo | A solid embryo without differentiated cotyledons; e.g., in Lecythis spp. (Lecythidaceae) and Monstera spp. (Araceae). | |
| Myrcioid embryo | A type of embryo found in the Myrtaceae in which the cotyledons are normally thin, leafy, and folded, and the narrow, cylindrical hypocotyl is about the same length as the cotyledons and encircling them. Compare with eugenioid embryo and myrtoid embryo. | |
| Myrtoid embryo | A variable type of embryo found in the Myrtaceae in which the hypocotyl is the same length or much longer than the cotyledons; in genera with hard seed coats, the embryo is C-shaped; in genera with membranous or submembranous seed coats, the hypocotyl often is greatly swollen, and sometimes the whole embryo forms a spiral. Compare with eugenioid embryo and myrcioid embryo. | |
