| The raphe is a slightly depressed area on the opposite side of the hilum from the micropyle. |
| The micropyle is the pore through which the radicle emerges during seed germination. |
| Only one pollen tube tip entered the nucellus through the micropyle. |
| The radicle and plumule form a small subglobose unit, the embryonic axis, whose acuminate lower end extends into the micropyle. |
| In a favorable situation, an opening called the micropyle appears and releases amoebocytes, which differentiate into cells of all the other types. |
| A nucellar dome has been formed in the massive nucellar cap and the integument has overgrown the nucellus and formed a wide-open micropyle. |
