Vedclass · Answer

(D) Gymnosperms and angiosperms are both seed-producing plants,but they differ significantly in their reproductive structures and development.$1$. In gymnosperms,the ovules are not enclosed by any ovary wall and remain exposed,both before and after fertilization. The seeds that develop post-fertilization are not covered,i.e.,they are naked.$2$. In angiosperms,the pollen grains and ovules are developed in specialized structures called flowers. The seeds are enclosed inside fruits,which develop from the ovary after fertilization.$3$. The endosperm in gymnosperms is formed before fertilization and is haploid $(n)$,whereas in angiosperms,the endosperm is formed after fertilization through double fertilization and is triploid $(3n)$.

Both gymnosperms and angiosperms bear seeds,then why are they classified separately?
