A large sheild-shaped catyledon found in some moncotyledonous seeds is
Open in App
Solution
The correct option is D Scutellum
A. Aleurone layer- In monocotyledonous
endospermic seed, endosperm 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 an important role at the time of
germination.B. Coleorhiza- Protective sheath of radicle.
C. Scutellum- In monocotyledonous endospermic seed, the embryo consists of an upper shield shaped scutellum wich 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.
D. Hilum- It is the point of attachment of the body of the ovule with the funiculus.
E. Coleoptile- Protective sheath of plumule.So, the correct answer is 'Scutellum'.
