The document discusses various transport processes in plants and animals. It covers cellular transport mechanisms like diffusion, osmosis, and active transport. It then discusses transport within plant cells and tissues, including the roles of xylem and phloem in long-distance transport. Xylem transports water and minerals upwards, while phloem uses a pressure-flow mechanism to transport organic nutrients throughout the plant. Stomata and transpiration help regulate water transport and loss in leaves.
