Solution:
Structures found in monocot seed:-Pericarp: It is also known as the fruit wall. The fruit wall is fused with the seed coat (integuments), and this type of fruit is known as a caryopsis. It is composed of sporophytic cell so it is diploid $\left(\right.2n\left.\right)$ in nature.
Scutellum:-They have a single cotyledon called scutellum. The main function of it is to provide nourishment to the developing embryo. It is the product of fertilization so it is diploid $\left(\right.2n\left.\right)$ in nature
Radicle, coleorhiza, plumule and coleoptile are present on the same axis called tigellum. All these structures are diploid $\left(\right.2n\left.\right)$ .
Endosperm:- The endosperm is the nutrient storage tissue, used up by the embryo to develop the scutellum. Aleurone is a proteinaceous layer that surrounds the endosperm of maize. Both endosperm and aleurone are formed after fertilization so that they are diploid $\left(\right.2n\left.\right)$ .
