Detailed explanation-1: -Bordered pits are cavities in the lignified cell walls of xylem conduits (vessels and tracheids) that are essential components in the water-transport system of higher plants.
Detailed explanation-2: -Tracheids perform conductive and mechanical functions. The intertracheid pits are quite specialized and have the most complex structure. These are usually circular bordered pits with a torus-margo pit membrane [1].
Detailed explanation-3: -So, the correct answer is ‘Metaxylem’.
Detailed explanation-4: -Bordered pits are cavities in the lignified cell walls of xylem conduits (vessels and tracheids), which are important components of higher plants’ water-transport system.
Detailed explanation-5: -Bordered pits are structures found in the conductive tissues of many plants that allow for fluids to pass from one cell to another. The tracheids, which transport liquids, are dead cells; their contents decomposed, they are essentially empty.
