They also absorb water and nutrients from the soil to be distributed to the rest of the plant. The stem of the plant supports the leaves and the flowers and serves as a transport for water and nutrients throughout the plant. Stems of some plants also carry out photosynthesis and make food for the plant. The leaves are where most of the photosynthesis occurs to make food for the plant's growth. The leaves also help the plant maintain the proper water balance through openings on their underside called stomata. Finally, the flowers of the plant make pollen to fertilize ovules that are also part of the flowers which will then produce the fruits that contain the seeds to produce the next generation of plants.
