Stem support and bears leaves, buds, flowers and fruits. Functions of the Brain Stem The brainstem regulates vital cardiac and respiratory functions and acts as a vehicle for sensory information. They supply signals that keep the stem cells from differentiating until they are called into action. However, stems are fundamental to plants and superbly adapted to the role they play. Stem arranges leaves in a way that it gets direct sunlight to perform photosynthesis. (ii) It carries water and minerals from the roots to the other parts of the plant.
