A) production of seeds from ovules
B) lack of xylem tracheids
C) absence of pollen tubes
D) formation of endosperm before fertilization
Correct Answer: D
Solution :
| [d] The conifers (gymnosperm) differ from the grasses (angiosperm) in the formation of endosperm before fertilization. In fact, in gyrnnosperms, the endosperm is formed, before die 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. |
| Xylem tracheids are present in both conifers and grasses. |
| Pollen tubes are also formed in both conifers and grasses. |
