Plants transport carbohydrates, primarily glucose, produced during photosynthesis via the phloem from sources (e.g., leaves) to sinks (e.g., roots, meristems). This process is called translocation.
O'simliklar fotosintez mahsulotlari bo'lgan uglevodlarni (asosan glyukoza) folem orqali manbalardan (masalan, barglar)Sinklariga (masalan, ildizlar, meristemalar) tashiladi. Bu jarayon translokatsiya deb ataladi.

| Back | - glucose (produced in leaf via photosynthesis) transported as sucrose, where it’s re-converted for respiration or into other compounds - plants transport organic compounds in phloem from sources to sinks (tissues that need them) during translocation, which is active process requiring energy, products of photosynthesis transported called assimilates, main assimilate is sucrose (from glucose) - main source of assimilates are leaves/stems, storage organs, food stores in seeds, some need transportation up and some need down plant - main sinks are roots (actively growing/absorbing mineral ions), meristems (actively dividing) or any part that is laying down food stores |
