Define the importance of the following structures in a monocot seed:
$(i)$ Aleurone layer
$(ii)$ Epidermal layer

(N/A) $(i)$ The Aleurone layer is a protein-rich layer that surrounds the endosperm in monocot seeds like maize. It plays a crucial role in the secretion of enzymes during germination,which helps in the breakdown of stored starch into simpler sugars for the developing embryo.
$(ii)$ The epidermal layer in a monocot seed refers to the outer boundary of the scutellum that remains in contact with the endosperm. It is involved in the absorption of nutrients from the endosperm and their transport to the growing embryo during the process of germination.
