The document provides information about photosynthesis and plant structures and transport systems. It discusses that photosynthesis mainly occurs in the palisade layer of leaves and involves the absorption of carbon dioxide and water and production of oxygen and glucose. It describes the chloroplast structure and the light-dependent and light-independent reactions of photosynthesis. Furthermore, it summarizes the role of xylem and phloem in transporting water, minerals and glucose throughout the plant.
