WebJun 8, 2024 · The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. The phloem transports the photosynthetic products from the leaf to the other parts of the plant. A single vascular bundle, no matter how large or small, always contains both xylem and phloem tissues. WebSeveral experiments have been carried out to improve our understanding of the phloem’s structure and function. In 1945, Rapeden and Bohr used radioactive 1 4 C to mark the carbon dioxide supplied to a species of bean plant. This radioactive carbon can be traced as it is used in the plant first during photosynthesis to synthesize carbohydrates.
