A) Lack of xylem tracheids.
B) Absence of pollen tubes.
C) Formation of endosperm before fertilisation.
D) Production of seeds from ovules.
Correct Answer: C
Solution :
Conifers (gymnosperms) differ from grasses (angio- sperms) because in gymnosperms the female game- tophyte is actually endosperm which is made before fertilization. While in grasses, endosperm is a tissue formed by the fertilization of second male gamete to polar nuclei. Moreover, the gymnosperms and the endosperm is a haploid tissue while in angiosperms it is triploid.
