The main function of the vascular system in plants is to transport water, nutrients, and organic compounds throughout the organism. Comprising two main types of tissues, xylem and phloem, the vascular system enables water and minerals to move from the roots to other parts of the plant and allows the distribution of sugars produced in photosynthesis. This efficient transport system is vital for plant growth, development, and overall health. The vascular system also plays a key role in maintaining turgor pressure, which is essential for keeping the plant upright and supporting its structures.
