Summary Introduction
Introduction:
Sugar and other dissolved nutrients move in phloem tissue of a plant. The phloem sap always flows from a region with a high sugar source concentration to a sink, which is a low concentration region. As a result of which, the cell sap can proceed in any direction.

Unlike the movement of water in the xylem, phloem sap movement is not defined by
gravity. It can move upward and downward in the plant. During very hot weather,
when the plant root is converting sugar to store as starch, state the role of root and
leaves.
Tidak seperti pergerakan air di dalam xilem, pergerakan sap floem tidak ditentukan
oleh graviti. la boleh bergerak ke atas dan ke bawah dli dalam tumbuhan. Semasa
cuaca sangat panas, apabila akar tanaman menukar gula untuk disimpan
kanji, kenal pasti peranan akar dan daun.
