e. the gymnosperms don't form flowers while the angiosperms do?

Answer 1

The answer is E

The gymnosperms don't form flowers while the angiosperms do. Gymnosperms are woody trees with cone like appearance. They bear no flowers, no fruits but bear seeds. The seeds are naked as they are not covered by the fruit wall. Gymnosperms produce naked seeds (a seed not enclosed in an ovary). In Angiosperms, the flowers are the reproductive organs and they may be both unisexual and bisexual. Angiosperms employ double fertilization resulting in a diploid (2n) zygote, and a triploid (3n) endosperm.
