The number of correct statements from the given statements is:
| I: | In a typical dicotyledonous embryo, the portion of the embryonal axis above the level of cotyledons is the epicotyl, which terminates with the plumule or stem tip. |
| II: | In a typical dicotyledonous embryo, the cylindrical portion below the level of cotyledons is hypocotyl, and it terminates at its lower end in the radicle or root tip. |
| III: | In the grass family, the cotyledon is called the scutellum, which is situated towards one side (lateral) of the embryonal axis. |
| IV: | At its lower end, the embryonal axis in monocots has the radical and root cap enclosed in an undifferentiated sheath called coleorhiza. |
| V: | In monocots, the portion of the embryonal axis above the level of attachment of the scutellum is the epicotyl. |
