Answer» Correct Answer - C (c) The conifers (gymnosperm) differ from the grasses (angiosperm) in the formation of endosperm before fertilisation. Infact, in gymnosperms, the endosperm is a haploid tissue as it formed before fertilisation, while in angiosperms, endosperm is formed after fertilisation as a result of triple fusionn of double fertilisation, 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. |
