Solution

The correct option is C a - Endosperm, b - Coleoptile, c - Scutellum, d - Epithelium
a) Endosperm- The food material is stored in this in maize for the development of embryo.
b) Coleoptile- Protective sheath of plumule.
c) Scuttellum- Reduced cotyledons.
d) Epthelium- The scutellar epithelium is a monlayer of cells in contact with the endosperm.
So, the correct answer is 'a- Endosperm, b- Coleoptile, c-Scutellum, d- Epithelium'.
