Definitions / Explanation :
$(i)$ Hypogynous flower / Superior ovary
$(ii)$ Scutellum

(N/A) $(i)$ In a hypogynous flower,the thalamus becomes cone-shaped,so the ovary is placed at the top. Such an ovary is called a superior ovary,and all other floral parts (sepals,petals,and stamens) are produced from below the ovary.
$(ii)$ In monocotyledonous plants,the embryonal region consists of one large and shield-shaped cotyledon,which is known as the scutellum.
