GeneralClass 12AllAnswered 27 Mar 2026
Answer
Solution:
The aleurone layer is the outermost proteinaceous layer of the endosperm in monocotyledonous seeds. It is rich in enzymes (e.g., α-amylase) that aid in starch digestion during germination. The layer separates the embryo from the bulk endosperm.
Example: Maize (Zea mays), wheat, rice.
Ploidy: Triploid (3n), formed during double fertilization.
