The answer is asexually.
The reason why plants that reproduce asexually than plants that reproduce sexually is because in asexual reproduction only one parent is needed, so there is no need for pollination and it is time and energy efficient. That means that farmers can grow large quantities for less time.
Answer:
Giving the Union control of the Mississippi River
Explanation:
The Union wanted control of the Mississippi to cut off trade and transport for the South. The river being taken also made things harder for the Confederates (because it cut their side in half, so the Union had the upper hand).
They sometimes grew food for the union army (while the plantation owners were away).
