Question

You are reading about a garden designer who has invented something called the "megagarden space" in which a few specimens are planted in a disturbed area and allowed to make a garden by self-propagation. Why might this designer choose to work with angiosperms rather than gymnosperms? Multiple Choice Angiosperms can produce flowers and fruits to aid in seed dispersal Angiosperms produce pollen and do not require water to reproduce. Angiosperms have alternation of generations Angiosperms have a vascular system, which allows them to grow taller.

Answer 1

Angiosperm has unique feature i. e. presence of enclosed ovule in the ovary. That's why after Fertilsation, ovary develops into fruit and ovule develops into seed. They also produce flower.  The presence of flower and fruit helps in seed dispersal in angiosperm. That's why Gardner chooses angiosperm.

Why other option wrong:

Angiosperm and gymnosperm both have alteration of generations. They both have vascular system.

Some Angiosperm also requires wind for pollination. And gymnosperm' pollen also pollinates stigma by means of wind.

Right option is:

angiosperm can produce flower and fruit aid in seed dispersal.
