Comment
The coleoptile is an outgrowth or part of the scutellum (PO:0020110) (which is a modified, haustorial cotyledon (PO:0020030)). Develops separate from the shoot apical meristem (PO:0020148). Found in Poaceae and other monocotyledons such as Zingiberaceae. Protects the emerging shoot system (PO:0009006) as it grows through the soil.
