Solution

formation of endosperm before fertilization

The conifers (gymnosperm) differ from the endosperm before fertilization. In fact, in gymnosperms, the endosperm is formed before the fertilization, thus, it is a haploid tissue while in angiosperms, endosperm is formed after fertilization as a result of triple fusion or double fertilization, thus, it is a triploid tissue.
In both conifers and grasses seeds are produced from ovules.
Xlem tracheids are present in both conifers and grasses.
Pollen tubes are also formed in both conifers and grasses.
