| Substantial phytase activity was found both in embryonic axes and cotyledons of dormant hazel seeds. |
| These embryos had organized root meristems and apical shoot meristems flanked by the developing cotyledons. |
| They are present on the stems, leaves, cotyledons, rachises, pedicles, bracts and calyces. |
| However, protein biosynthesis in the axis organs and cotyledons of dicotyledonous seeds commences much earlier. |
| Mutants of this class display shortened hypocotyls and small cotyledons after irradiation of seed. |
| The nodules were wrapped by anastomosing networks of blood vessels, reminiscent of the cotyledons of a placenta. |
