Which one of the following statements is correct?
Correct answer: C. A proteinaceous aleurone layer is present in maize grain.
- A. The seed in grasses is not endospermic
- B. Mango is a parthenocarpic fruit
- C. A proteinaceous aleurone layer is present in maize grain.
- D. A sterile pistil is called a staminode
Explanation
(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 interior of the grain and consists of two parts, hornyaleurone layer and mainly the 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 mobilize stored nutrients.
