Statement P: A meristem can give rise cells/tissues having different structures at maturity.
Statement Q: Vascular cambium forms cells towards interior of axis that mature to transport mineral and water and those cells formed towards the periphery mature to transport organic food materials.
Plants show open form of growth and differentiations. The types of cells formed from a meristem is dependent on the position of cells in the plant body. Vascular cambium forms secondary xylem towards the center that transports mineral water and secondary phloem towards the periphery that transports organic food materials.
