Answer
Correct option: C.
A proteinaceous aleurone layer is present in maize grain.
c
(c) : Grass seeds are endospermic. Mango is a seeded fruit. A sterile pistil is called pistillode and a sterile stamen is called staminode. Maize grains consist of fruit wall, seed coat, endosperm and embryo. The endosperm occupies most of the grains interior and consists of two parts, hornyaleurone layer and mainly storage layers. The aleurone layer lies immediately below the grain covering and is $13$ cell thick. Aleurone cells are thick walled with cytoplasm filled with aleurone grains which produce enzymes during seed germination to mobilise stored nutrients.
