Solution

i. The part that develops into seed coat− Integument

ii. The part that develops into an embryo after fertilization − Embryo sac

iii. The part that develops into an endosperm in an albuminous seed − Nucellus

iv. The part through which the pollen tube gains entry into the embryo sac − Micropyle

v. The part that attaches the ovule to the placenta− Funicle

Concept: Pre-fertilization in Plant: Structure and Events - The Pistil, Megasporangium (Ovule) and Embryo Sac
