Hint:After fertilization, the female reproductive organ carpal goes under a lot of changes. The style and stigma part of the carpel get degenerated and the ovary gets converted into the fruit. The ovules present inside the ovary become seeds.
Complete answer:
Let us look at the given statements individually.
a.The wall of the ovary after fertilization forms the pericarp.
As we know, once the process of fertilization takes place, the female flower transforms into the fruit. The wall of the ovary becomes the fruit wall after fertilization which is known as the pericarp. Depending on the ovary wall, the fruit can be a fleshy fruit or a dry and hard fruit. The ovary wall is made up of three layers known as the inner endocarp, the middle mesocarp, and the outer exocarp.
b. Betel nut is a one-seeded berry.
Betel nut is a berry as it develops from a one-seeded ripened ovary which is soft when fresh because of fibrous texture but becomes hard and nut-like once it becomes dry.
c. The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit.
The hilum is the scar by which the seeds were attached to the ovary with the help of a stalk known as the funicle.
Hence, the correct answer is option ‘C’ i.e, Pericarp, Berry, and Hilum'.
Note:
-Testa and tegmen are the outer protective covering of the seed that is formed by the integuments of the ovule.
-The micropyle is a tiny pore present in the testa from which water enters during germination.
-The end opposite of the micropyle in an ovule is known as the chalazal end.
