Question

In the monocotyledonous seeds, the endosperm is separated from the embryo by a distinct layer known as

• A. testa
• B. aleurone layer
• C. coleoptile
• D. scutellum

Answer 1

The correct option is B aleurone layer

In monocotyledonous seed, the covering of grain encloses two major parts, endosperm and embryo. In longitudinal section, the major portion of grain is occupied by a large starchy endosperm. It is surrounded by a special one-cell thick layer. Called aleurone layer. The cells of aleurone layer are filled with proteinaceous aleurone grains which play in important role at the time of germination.
