Question

In a velvet grass seed, the cotyledon is called:

• A. Scutellum
• B. Coleorrhiza
• C. Coleoptile
• D. Testa

Answer 1

The Correct Option is A

In grasses like velvet grass, the cotyledon is termed the scutellum. It is a specialized structure that facilitates nutrient transfer from the endosperm to the developing embryo in monocot seeds.

Answer 2

In the seed of velvet grass (and other monocots like grasses), the cotyledon is modified and is known as the scutellum. The scutellum serves as a food storage organ that provides nourishment to the growing embryo during seed germination.

• Coleorrhiza refers to the protective sheath around the embryonic root in monocot seeds.
• Coleoptile is the protective covering that surrounds the shoot in monocots.
• Testa is the seed coat that provides protection to the seed.
