Task: Text Categorization
Input (English): The secondary type of this tissue is produced on the adaxial side of the vascular cambium, whereas the primary type of this tissue is located closest to the pith. Tracheids and vessel elements make up this tissue, and one mechanism for its function involves the evaporation of water at the mesophyll cells in leaves and the resulting pressure at roots called transpirational pull, which allows water and minerals to travel through the plant. For 10 points, identify this type of vascular tissue in plants that is complemented by the phloem.
Output (English): Science
