The correct answer is: Movement can occur both upward and downward in the plant.
Phloem is a plant tissue (in vascular plants) that transports the organic compounds made during photosynthesis in the form of sap-water based solution rich in sugars. Phloem is composed of living cells generally called sieve elements. Transport of sap is multidirectional: sometimes sugars made in photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots but sometimes roots are sugar sources so the sap needs to be transported upward for the plant’s growth.
The answer is hydrogen bonds between the complementary bases are are broken.
