Correct Answer: C
Solution :
Caruncle is a fleshy, whitish structure present on the micropylar end of the seed. It arises due to the proliferation of cells at the tip of the outer integument, on the side of the funiculus or all round the micropyle. At least two functions have been discribed to the caruncle : (i) being sugary it is eaten by ants which helps in seed dispersal and, (ii) by virtue of being hygroscopic it absorbs water from the soil and passes it on to the embryo during germination.
