Webb18 nov. 2024 · Xylem and Phloem are two different types of vascular tissues, which are mainly involved in the transportation process. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids from the leaves to other parts of the plant.

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.

Webb7 jan. 2009 · Solute transport between plant cells occurs either through plasmodesmata or across the apoplast. Since Suc can enter the phloem in the minor veins of leaves by one or the other route, depending on species (Schulz, 2005; Turgeon and Ayre, 2005), it is reasonable to suspect that sugar alcohols have the same opportunities. WebbIn plant anatomy, there are two main types of sieve elements. Companion cells and sieve cells originate from meristems, which are tissues that actively divide throughout a plant's lifetime. They are similar to the development of xylem, a water conducting tissue in plants whose main function is also transportation in the plant vascular system. [1]
