The distinct whitish oval scar on the concave side of the seed is termed as :
- Scutellum
- Micropyle
- Hilum
- Germpore
Answer
Hilum
Reason — Hilum is the distinct whitish oval scar on the concave side of the seed which represents the spot where the ovule was attached to the ovary wall.
The scutellum is a structure of the embryo in monocot seeds. The micropyle is a tiny pore in the seed coat through which water enters during germination. It is not the whitish oval scar. Germpore is not a standard botanical term used for seed structure in this context.
