WebbPhloem is a class of complex permanent tissue that develops into a conductive or vascular system in the plant’s body. It transports the prepared nutrients from the leaves to the growing areas and storage organs. It is also considered that vascular plants’ phloem sap contributes to the transmission of informative signals. Related Links: Webb3 nov. 2024 · Biology definition: Xylem is a type of vascular tissue in plants. It is primarily involved in transporting water and minerals (from the roots to the shoot and leaves) and providing structural support. It is found in the stems and leaves of vascular plants. Etymology: Greek “xylon”, meaning “wood”. Compare: phloem.
