Plants take water and minerals from the soil through the roots and transport it to the leaves. The leaves prepare food for the plant, using water and carbon-dioxide during photosynthesis.
This process of photosynthesis prepares food for the plant which is necessary for energy to the cells. The cells use this energy to carry out vital activities of life. Therefore, food must be made available to each and every cell.
Thus, a proper system of transportation is required for the transportation of food, water and minerals. This system of transportation includes:
