Plant vessels are specialized structures in plants that transport water, nutrients, and sugars. There are two main types of vessels: xylem and phloem. The xylem carries water and minerals from the roots to the leaves, while the phloem distributes the sugars produced during photosynthesis throughout the plant. These vessels are essential for plant growth and health. They are made up of elongated cells that form tubes, allowing for efficient movement of substances. The proper functioning of plant vessels ensures that all parts of the plant receive the necessary resources to thrive.
