Plants take in water, minerals, carbon dioxide, and sunlight for nutrition. Roots absorb water and minerals to create raw sap, which travels to the leaves through woody vessels. Leaves absorb carbon dioxide and sunlight to create elaborated sap, which travels through liberian vessels to the rest of the plant. Plants reproduce sexually with or without flowers through pollination or asexually by tubers, bulbs, rhizomes, stolons, or cuttings.
