The correct answer is option 4, xylem. Xylem is a specialized tissue in plants responsible for transporting water and minerals from the roots to the rest of the plant. It is a complex network of interconnected cells that form hollow tubes. These tubes allow water to move upwards against gravity, from the roots all the way to the leaves and other parts of the plant. Xylem also provides structural support to the plant. Cambium, mentioned in option 1, is a different type of tissue responsible for the secondary growth of plants, not water transport. Option 2, phloem, is the tissue responsible for transporting sugars and organic nutrients throughout the plant. Epidermis, mentioned in option 3, is the outermost layer of cells on the plant`s surface and acts as a protective barrier.
