Options
- AThe seed in grasses is not endospermic.
- BMango is a parthenocarpic fruit.
- CA proteinaceous aleurone layer is present in maize grain.
- DA sterile pistil is called a staminode.
Correct answer
C. A proteinaceous aleurone layer is present in maize grain.
Step-by-step solution
The seeds in grasses are endospermic and massive endosperm stores food which provides nutrition to embryo during germination. The outermost proteinaceous layer of endosperm is called as aleurone layer which is present in maize grain and other members of Poaceae family. Sterile stamen is called as staminode. Mango is a true fruit which develops from monocarpellary ovary and has single seed.
