Question

The point at which funiculus touches the ovule is
A) Chalaza
B) Hilum
C) Raphe
D) Endothelium

Answer 1

Hint:Funicle is the stalk which attaches a seed or ovule to the placenta and ovule is the structure which gives rise to the female reproductive cells.

Complete answer:
Let us analyse the options to find the correct answer,

Option A: The chalaza is the part of the ovule which is present opposite to the portion of attachment of nuclellu, funiculus and integuments. Therefore, this is the incorrect option.
Option B: The point at which funiculus touches the ovule is hilum. The hilum in plants can be compared to umbilical cord in humans. Therefore, this is the correct option.
Option C: Raphe is basically the ridge which shows the fusion of funiculus with the body of the ovule. Therefore, this is the correct option.
Option D: The specialized tissue which is present around the embryo sac is known as endothelium. Therefore, this is the correct option.

Therefore, the correct option is (B) Hilum.

Note:Seeds are a very important part of a plant, as they have the ability to give rise to a whole new plant. There are three parts in a seed,
Seed coat - It is present as the outermost layer of the seed
Embryo - It is developed from a fertilized egg and is diploid in nature
Endosperm - It contains nutrients
