the covering of the young shoot of the embryo of a grass seed
A protective sheath for the young shoot in the embryo.
A protective cylindrical sheath-like structure that surrounds the shoot apex in cereal and grass embryos.
Protective structures found in monocot seeds that cover the embryonic shoot bud or plumule
KOL-ee-OP-tile A sheathlike structure that covers the plumule in monocots. 568
A sheathlike structure covering the shoot of grass seedlings.
The leaf sheath which surrounds and protects the embryonic plant as it emerges from the seed.
(coal-ee- op-tile) [Gk. koleon, sheath + ptilon, feather] The sheath enclosing the apical meristem and leaf primordia of a germinating monocot.
(pl. coleoptiles): In a plant, the first leaf of a monocotyledon forming a protective sheath around the plumule
Protective sheath around epicotyl in grasses.
The sheath that encloses the first main shoot leaf and provides protection as it emerges from the soil.
Coleoptile is the pointed protective sheath covering the emerging shoot in monocotyledons such as oats and grasses. Coleoptiles have two vascular bundles, one on either side. Unlike the flag leaves rolled up within, the pre-emergent coleoptile does not accumulate significant protochlorophyll or carotenoids, and so it is generally very pale.
