In a velvet grass seed, the cotyledon is called:

The correct answer is Option (1) → Scutellum

Velvet grass belongs to the grass family, so its seed has a monocot embryo with one cotyledon.

Option (1) Scutellum — Correct. The single cotyledon of a grass embryo is the scutellum, placed to one side of the embryonal axis.

Option (2) Coleorrhiza — Incorrect. The coleorrhiza is the sheath round the radicle and root cap, at the lower end of the axis.

Option (3) Coleoptile — Incorrect. The coleoptile is the hollow leaf-like sheath round the shoot apex, at the upper end of the axis.

Option (4) Testa — Incorrect. The testa is the outer seed coat, formed from the outer integument of the ovule. It is not part of the embryo.

NCERT Extract:
Embryo – “… Embryos of monocotyledons (Figure 1.14 b) possess only one cotyledon. In the grass family the cotyledon is called scutellum that is situated towards one side (lateral) of the embryonal axis. At its lower end, the embryonal axis has the radical and root cap enclosed in an undifferentiated sheath called coleorrhiza. The portion of the embryonal axis above the level of attachment of scutellum is the epicotyl. Epicotyl has a shoot apex and a few leaf primordia enclosed in a hollow foliar structure, the coleoptile.”
