Which of the following is a correct statement about sugar movement in phloem?

sugar transport does not require energy.
sugar is translocated from sinks to sources.
movement can occur both upward and downward in the plant.
diffusion can account for the observed rates of transport.
only xylem cells can perform sugar movement

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.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
