| Thus the three seed components, embryo, endosperm and seed coat, are genetically distinct. |
| Tobacco seeds accumulate oil and protein in the embryo, cellular endosperm and inner layer of the seed coat. |
| At maturity, the seed coat is primarily a protective structure, although its specific role may be varied and complex. |
| The layer between seed coat and cotyledon probably includes the wall of the embryo sac. |
| A seed was regarded as germinated when the radicle protruded through the seed coat. |
| In general, the innermost layer of the seed coat of legumes consists of irregularly shaped cells with large intracellular spaces. |
