Question

In monocotyledonous seeds, endosperm is separated from embryo by a distinct layer of

• A. Testa
• B. Tegmen
• C. Aleurone layer
• D. Scutellum
• E. Coleoptile

Answer 1

Answer: (D)

Scutellum

In monocotyledons seeds,

A. Testa- Outer covering of seed.

B. Tegmen- Inner covering of seed.

C. Aleurone layer- Endosperm is surrounded by a special one- cell thick layer, called aleurone layer.

D. Scutellum- The embryo consists of an upper shield shaped scutellum which is actually a reduced cotyledon. The scutellum is closely pressed against the endosperm and helps in the translocation of nutrients from endosperm to the growing embryo at the time of germination and seedling growth.

E. Coleoptile- protective sheath of plumule.

So, the correct answer is 'Scutellum'.
