Webb21 sep. 2024 · The phloem moves food substances that the plant has produced by photosynthesis to where they are needed for processes such as: growing parts of the plant for immediate use. storage organs such as ... WebbSugars (usually sucrose), amino acids and other organic molecules enter the sieve elements through plasmodesmata connecting them to adjacent companion cells. The movement of food through the phloem is bidirectional i.e. both in upward and downward directions (bidirectional).
Phloem Transport Flow from Source to Sink - unacademy.com
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. Xylem moves water from roots to the … Webb11 jan. 2024 · Since the source and the sink may change their position, the movement is bidirectional. Does phloem transport glucose up or down? Unlike the xylem, which can only carry water upward, phloem carries sap upward and downward, from sugar sources to sugar sinks: Sugar sources are plant organs such as leaves that produce sugars. share refund warrant

WebbQuestion 1: Movement of substances in xylem is unidirectional while in phloem it is bidirectional. Explain. Answer: Xylem transports water. Since transportation of water always takes place from roots to leaves, the direction of transport always remains in the … Transpiration is the process in which plants release the water inside it in the form of … Transport in Plants 1.
